Description

106058Z
The invention relates to systems for transferring and exchange data between at least two populations of people nes.
Such systems are known. In particular, the bre-vet US n ~ 3,702,464 describes a compound system - on the one hand, at least one portable object comprising a memory, - on the other hand, a number of peripheral units geographically dispersed connected to a central computer carrying a central recording memory.
The peripheral units include means of command to control the transfer of data between the central computer memory and portable object memory when the latter is coupled to the peripheral unit considered.
Such a system, whatever the degree of organization portable objects, peripheral units and the computer central, has a major drawback. Indeed, it requires a network of complex interconnections between the central computer and peripheral units. The result is:
- on the one hand, installation costs ~ raised, - on the other hand. compromised reliability of the ~ has disturbances likely to affect the interconnection network (aus ~ i ~ labor ~ es ~ ~ have these interconnections).
The invention aims to avoid the disadvantages of sy ~ t ~ me ~ known ~ while allowing ~ ant to group. eco-friendly nomic and ~ reliable, the donrlées of provenances ~ eographic dif-~ renteq to a central organization.
To overcome the drawbacks of known systems, the inventor had the idea, against the current of central trends 4atrice ~ dominant in her time, to achieve a plurality of d ~ 4 independent, autonomous devices, comprising ~ means (moy-in ~ registration, etc ...) to transfer to ~ lace - 1 _:
~ 06 ~ 582 data between the memory of the portable object and the device considered.
So, according to the main feature of the pr ~ -invention, the system for exchanging and transferring data born between at least two populations of people (people of each of these two populations being geographically dispersed persées) includes:
- a plurality of specific recording devices very independent, distributed in places geographically ~ -defined, - a plurality of portable, electronic, portable objects parties between people from one of the populations who carry on them.
These portable objects each include:
- a memory; preferably this memory is incorporated inaccessible inside the portable object, preferably also this memory is dead, not supplied.
of the semiconductor type, - coupling means making it possible to couple to will, temporarily, one of said portable objects with one of said specific recording devices or with one of-said writing arrangements, - of ~ memory control circuits in ~ erconnected between the means of coupling and memory the m ~ mix and the ~ mo ~ control set being made in the form of micro ~ tructureslo ~ iques.
These portable objects are intended ~ s to memorize, under u-ne ~ elm ai ~ ment transportable, data ~ es to transfer.
Each recording device includes:
- a means of reading the contents of the memory of the ob-portable jet when the latter is coupled with the device specific recording, .
10 ~ 58Z
a means of recording the content of the memory of the portable object interconnected with said reading means.
Thanks to this set of means, each person can receive, in the form of recording, the contents of the memories of each portable object without the need for a pass-serv via a central computer.
In addition, so that each person in one of the popula-tions can receive data from people of the other popu-lation and vice versa, the system further comprises, according to a complementary characteristic of the invention, a plurality independent writing devices, distributed in places geographically defined; moreover, the memory of the portable object has programmable recording sections, each positive writing includes a means of registration allowing to write data in the object's programmable memory portable when the latter is coupled to the writing device.
Thanks to this set of additional means, it is possible to write data in the memory of each of the objects tatives.
Preferably, the means of registration, reading and are interconnected and contained in one ~ available transfer. This is particularly the case in applications which will hereinafter be considered but this is available to you.
tlon particular is not essential.
Such a system can be used in various ways, may consider using it to keep a health record:
- the patient has a health book ~ in the form- '~
me of a portable electronic object) containing in memory the various medical information concerning him, - the doctor he will consult - who is not born -his usual doctor - has a device (specifically fi ~ ue) allowing it to read the contents of the notebook's memory and save to another memory available to him tion the information it needs to establish its diagnosis tick then write down in the memory of the health book the nièreq medical information concerning the patient.
According to another main characteristic of the pre-invention, the recording means is composed:
- on the one hand, a means of registration located inside of the specific recording device, - on the other hand, at least one portable object comprising . a memory having recording sections programmable, in particular irreversibly, preferably, this memory is a read-only memory, not supplied, of the type with semiconductor: preferably also it is incorporated inaccessible inside said portable object, . coupling means accessible from outside eur connected to the memory allowing to couple at will tem-porally said portable object with the means of registration of-said recording medium, . of 3 interconnected memory control circuits ~ 0 t ~ s to the coupling means and to the memory, the m ~ memory and the control means being produced ~
SOU9 form of ~ logical ~ micro-structure.
Thanks to this particular structure of the recording means overall, it is possible to memorize, to transfer periodically only, conveniently and easily to a computer central for example, le9 d ~ e ~ ~ regroup it suf ~ it trans-mottr ~, by carrier, by mail, by tire etc ... the object portable in the place where the central computer is located, the latter;
ost. adapts so as to read the contents of the object's memory portati ~.
It is emphasized that this original solution consisting in use two portable objects and a transfer device 106058 ~
place of an interconnection system is actually more economical and more reliable than this interconnection system and that it con ~
comes perfectly for transferring a small amount of data spread over a relatively long period of time.
such a system can be used to keep an account in the bank. For the purposes of this partial banking application the system is also designed to transfer data born confidentially for this purpose and according to a charac-complementary teristics of the invention:
each of said portable electronic objects comprises another programmable memory containing the identity data tification programmed once and for all, - each of said transfer devices (for recording trement and / or writing) includes an identification comparator tion designed for:
. compare the identification data contained in said other memory to a datum introduced in the provision transfer of the portable object, . authorize the implementation of the means of the transfer when there is concordance between the data ready.
Let us briefly recall what are the operations at ef--~ perform for a bank account and how 1Q system ~ me which has just been described can atxe used ~ for ten ~ r a bank account:
1 ~ - the buyer holding a payment card (the ~ and portable) lns ~ re the latter in the trans-f ~ rt (~ also called otherwise specific device) located.:
at the point of sale (more generally the place where the buyer must pay for purchases) ~ -

2 ~ - the transfer device controls the identity of the.
payer by comparing the identification data contained in .,., .... ~, _ -. :. ,, the payment card with the confidential code entered directly-ment in the device by the payer.

3 ~ - the transfer device determines the balance credit from the information on the card and compare it to the amount of the purchase entered directly into the cashier transfer device.

4 ~ - the transfer device registered in the card of payment from the payer the new available balance (less than anterior balance).

5 ~ - the transfer device recorded in a memo-re at the merchant's disposal (memory produced under the form me of a portable merchant card) the bank details of the payer and the amount of the purchase. :

6 ~ - the merchant then communicates with his banker ~
merchant card containing the bank details of its customers - '' ents and the amount of their purchases so that it is done pay by the bankers of the various payers the amount of purchases and credits the merchant's account with its amounts.
We will now describe by way of non-limiting examples tifs some variants of realization of the system according to the invention tion by referring to the figures which represent:

The following descriptions call for the begin-following general mayors.
All the variants described are more particularly intended for banking and accounting applications because of this, and in order to make it easier to read, we have ment employed to expose their mode of operation a termi- ~ ' nology specific to banks and to the maintenance of a bank account.
The devices described may, however, have any other applications and can be used in any application where it is necessary to transfer data between people geographically dispersed and where it is necessary to group all or part of this data to a single central body.
~ e ~ circuits ~ electronic portable objects ~ memory-r ~, etc ...) are, due to their banking application. incor-pore ~ so inacce re ~ sihle dan ~ portable obje ~ (so that we can not easily le9 fraud easily): this last pr ~ feel in particular ~ ous the shape of a flat rectangular map-r ~ I ~ are incorporated in an inaccessible manner in these cards, that is to say that it is not possible to access the circuits electronic san ~ destroy them- we can achieve this by paxticulier by realizing them in the form of electric micro-structures tronic (integrated circuits whose components are hardly i-~ 0 ~ 05 ~ Z
dentifiable under the microscope) and by embedding them in an opaque plastic resin. Other mechanical solutions are, of course tense, possible. The coupling means are the only ones elements allowing electrical or optical access to electronic components contained in the card.
Note however that these additional technical precautions information, essential in the case of banking applications to prevent fraud attempts, can be superfluous roofs in other applications where the risk of fraud is 10 nonexistent.
Finally, note that the monolithic read-only memories with semiconductors used in these variant embodiments and incorporated into the cards can be of different natures tes: in particular of the programmable or reprogrammable type. Like-memories do not need any energy for memorization informations. However, writing information requires usually a significant amount of energy (several watts instantaneous) ~ therefore the manufacturers guarantee a du-infinite storage capacity (in the case of program memories bles) or extremely long: of the order of several tens years (in the case of reprogrammable memories). We can ci- ' ter as a reference for this type of memory3:
- H ~ RRIS 7620, MONOLITHIC MEMORIES 6340, TEX ~ S INSTRU-M ~ NTS 74 S 387, INrrERSIL 5604, these m ~ moirRs not e ~ a ~ cables (des-tructibl ~ s) are of the ~ ~ type usable or breakdown of junctions.
- INTEL 170 ~ and NATIONAL SEMI CONDUCTEUR 5203, the latter ni ~ res m ~ moires are e ~ shaped by exposure to a source of ultraviolet rays or X-rays.
~ es capacit ~ s of 4096 bits are manufactured ~ uées fluently by some manufacturers, particularly in the field of memories MOS ~ erasable), Modern methods of interconnection of integrated circuit pads thus make it possible to achieve ~ OtO582 inexpensive a block of memory of 16 kbits or 32 kbits (4 or 8 pellets) over an area of a few tens of mm2, so that such a memory block can be included in a card for before having the following dimensions 2 x 60 x 80 mm.
These solid state monolithic read only memories compared to other memories such as: "casset-your "magnetic, flexible discs, etc ... appreciable advantages ables. Indeed, they are more reliable, their dimensions are smaller, they do not require mechanical movement;
they are insensitive to magnetic fields, they are diffi-eyelashes to counterfeit and to violate (the fraudster must implement See complex electronic means to modify the state of semiconductor type read only memory).
Therefore, these semi-conductor type read only memories are particularly well suited to be used, preference to others, in memory systems and data transfer according to the invention ~ in particular, in the applications of these systems for banking and holding a bank account.
We will now describe a transfer device (a specific device) more particularly used for distributing drink banknotes referring to Figures 1, 2, 3.
The system consists of two separate parts which, in ~ service, are connected by an interface symbolized by a line in very mixed, namely:
- on the left a portati ~ object, not powered, advantageous-~ ement a ring, a card, a pendant, a pen, incorporating a certain number of electronic circuits (for example 8 ~ according to the technique of integrated circuits): said circuits 30 ~ electronics containing memories with integrated circuit, avanta-; ~
storing programmable read only memories tProgrammable read only memory). ~ -_ 9 _:
106058 ~
- on the right a specific device, advantageously a bank machine, or cash register for direct use at a point of sale, in the latter case, the debit transaction written below does not take place.
not a supply of banknotes but the ins-description in the merchant's cash register of information later allowing the latter to obtain:
share of the ring bearer's bank consideration in return fiduciary or scriptural information.
For clarity, we will retain in the context of this description the assumption of a ticket distribution of bank, also strictly equivalent on the electro-fuck, assuming a cash register.
Ring circuits including an ID memory:
tification (40), a debit memory (50) and a creation memory:
says (51). The system allows during the same use the following operations:
- identification of the wearer of the ring, an operation which authorize or re ~ use the rest of the process, - possible reading of a document assigned to an "auto-crediting "and recopies the amount to be credited from this cument in the ring's credit memory:
- debit bit in ar ~ ent liquid of a sum requested ~ e ~ i, and only if the state of the ring bearer's account allows it and taking into account the amount of this sum:
- recording of the whole process, ~ accounting and / or eventual ~ subsequent checks, 9ur a support such as m ~ moire ~ semiconductor, tape or disk magneti ~ ue. cassette, etc ............................................... .: ~
The operations to be carried out by the wearer of the ring are the following: :
- possible introduction of a credit authorization ~.

106 () 58 ~
in the player (1141, - dialing of the confidential identification number on the keyboard (31), - possible composition of the amount to be debited on the keyboard (~ 3), these first three operations can be performed killed in any chronological order, - then, introduction of a projecting part of the ring in a corresponding housing provided on the housing of the tributor.
When the wearer of the ring makes the last:
re operation which falls to him, namely the introduction of the ring in the dispenser, all the operations listed above are done very quickly. Almost instantly, the dis-positive will have finished operating, allowing one of the following results.
possible according to the choice of the wearer of the ring and the condition from his account:
- simple verification of the account status by display numexique of the balance on display 69:
- checking the account status after introduction a sum to be credited by introducing an authorization for cr ~ dit, which is absorbed, erased or destroyed in a manner not rep ~ ent ~ e, after ~ entry of the amount to be credited in the moire de cr ~ dit du ring:
- verification of the state of the account apx ~ introduction de cr ~ dit et op ~ ration de debi ~ ~ n cash pax le di ~ tri-:

ti ~ QU void of the new balance.
For accounting and / or subsequent control purposes ~,. ,,. ~. .

eventual, the whole process triggered by the introduction of a ring in the distributor is saved inside the dispenser, on a support such as tape or magnetic device that, semiconductor memory, etc ... To this end, the conduc-teurs 90, 91 and 92 route to the recording device 95 noted ENR the information exchanged by the rings and the tributor during cha ~ ue operation of the distributor.
Similarly, in order to provide the wearer of the ring with a written record of the operation performed, a printing device 96 noted IMP is connected in parallel on the recording device registration 95.
The method, applied to a cash dispenser bank, can also be applied directly to a point of sale, which allows the wearer of the ring to make purchases, the amount of the amount due being paid neither in cash nor by each, but simply by the fact that the ring of the purchase the debtor is debited for the amount of said sum; note here the utility printing and recording devices 96 and 95 which simplify significantly trust the seller's accounts and allow him to adjust his situation with the bank without having to handle large sums of cash, it should be noted, in this last ca ~, that the usual circuit of cash enters bank, account holder, seller and bank is thus eliminated ~
by 1 ~ set of 9 credit vouchers and vouchers printed by the body 96 with, in both cases, identification of the account holder.
We will now describe the following di ~ erent sequences boasts ~ of ~ unctioning of dispoqitif:
- ring feed, - initiation of the general piloting of the different or-ganes of the device by triggering of the multiplexer (38);
- operation of one of the three memories (for example-full reading of the identification number, Figure 2):

10 ~ 58Z
- operation of one of the two sub-adders sequential tractors (marked AS / S), (for example works-ment of the adder (32), FIG. 3), - reading of previous credits, - writing of the new credit, - reading of previous debits, - writing of the new flow.
The cash dispenser device includes a bone power cillator (150) which feeds a winding (151).
When the ring is adapted to the distributor, the main winding mayor (151) is coupled to a secondary winding (105) which is part of the circuits of the ring: this winding provides a-then, through a rectifier assembly comprising a diode (106 ~
and an electronic capacitive filter (107), a conti-bare intended for the various supply circuits of the ring.
Optionally, this electromagnetic coupling is re ~ placed by a optical coupling, the members (150) and (151) being replaced by a light source and the winding (105) by a photocell voltaic. The coupling of the ring and the distributor takes place simply by introducing a protruding part which comprises the ring in a housing ~ corresponding pr ~ seen on the case of the dis-tributor. This introduction has the effect of closing by pushing m ~ canique a contact ~ 27) which ~ is part of ~ n di ~ positi ~ not re-pr ~ ent ~ general supply of ~ circuits of the distributor tickets. Simultaneously, the timer (28) has been triggered, which apply a level to the 1 ~ a first entry of the OR gate (41), this level 1 ~ t maintained pendan ~ a temp ~ sufficient ~ ant for the donti ~ ication of the wearer of the ring can be carried out normal-is lying; note that the second entrance to the OR gate (41) which corresponds to the output of the flip-flop (42) eqt then set to 0 by ba ~ culement dQ flip-flop (42) caused by the appearance of a level 1 on its clear entrance through the OR gate (86). If this :. '.

identification test succeeds (we will see below in which the conditions and what that entails) the binding of food tion is maintained until the end of operation of the dispenser thanks to the presence of a level l on a second entry from the OR gate (41).
The presence of this signal, which means that the user has used a false identification number, however removes the power supply link by presence of UIl level zero on the two OR gate inputs (41), level l on the first entry having dropped to zero and level l on the second entry has not been established, so the distributor cannot be used. The material realization of the device (28) is at the scope of the skilled person.
It should be noted that the entire device described here is wired in positive logic.
- Start of general piloting.
When a logical level l appears in one of the two inputs of the OR gate (41), it is transmitted through this gate te El '~ 34) and, in parallel, with the ascending monostable (35), the monostable ascending (35), the stable state of which is indicated by guard of each of se9 two outputs by l and 0, sends a pulse slon of additional value (1 on the output marked 0 and 0 on the output not ~ el) at the appearance of a ~ ront rising in-very ~ during the duration of the pulse emitted by the monostable ~ 35), 1A ~ oxtic not ~ el transmits a level lo ~ ique ~ ero on a second-me ~ ntr ~ e of the door AND t3 ~) which re ~ te ain ~ i blocked ~ e ~ the second-me ~ nettle of the ascending monostable (35) sends a posi-tive ~ ur the entry ~ e reset to z ~ ro of the counter ~ 36) which is the pilo-te of the t38 multiplexer). At the end of the pulse emitted by the monostable ascending ~ 35), the state ~ table l appears on the output not ~ el of the latter, which has the effect of opening the door AND
~ 3 ~). This then lets pass a first supplied pulse , ~ 060S8Z
by the clock oscillator (33), this pulse, transmitted to the counter (36), puts the demultiplexer (38) on its first position, the exit position denoted 0 corresponding to the conduc ~
tor noted (160) ~ it is transmitted simultaneously to the input of the descending monostable (37), which functions like the monosta-ble ascending (35), except that it sends a pulse output sion only on falling edge input, this impulse, positive on the output marked 0 of organ 37, is transmitted through the demultiplexer (38) on its output marked 0, after this impulse, this part of the device remains inert until the next pulse from the oscillator appears-counter (33) and the cycle repeats, identical to the previous one, the counter tor (36) passing the demultiplexer (38) from the output no-tee 0 at the output marked 1, said next pulse emitted by the oscillator-clock (33) being transmitted with delay and after fitness by the descending monostable (37), at the exit rated 1 (general reset RG noted (161) of the demultiplexer (38)), the operating cycle is thus described successively-ment for the ten ~ output states of the multiplexer (38), the eight the latter also transmit an impulse in sequence positive to the same general clock conductor (162) through the OR gate (39), it should be noted ~ ue the ~ state of ~ nettle noted (~) of multiplexer (38) is immediately followed, in the operation mont r ~ current previously described, by the output state noted 0 it is by this part of the device ~ eu 9 1 ef ~ ectue piloting of ~ yst ~ me throughout the duration ~ e of ~ unctioning, as we we will see below, Outside of the ring circuits supply, the transmission of information ~ between ring and distributor is eff ~:

Upon the appearance of a positive impulse at the exit tie 0 of the ascending monostable (35), a logical level 1 is transmitted through the door or (60) and the optical coupling (45) at the memory reset input, which stalls on the first page the credit (50) and debit (51) memories, for initiation reading of the subsequent reading process (by page, we mean a set of several parallel memory points, each of them be them corresponding to a non-passing or passing state according to whether it was written or not and this in an irreversible way). This level also places in counting position 0 adders sequential subtractors (32) and (49) and resets the comp-tor (47), as for the memory (40), it is permanently locked on the first page by a constant level 1 on its entry re-memory reset (level symbolized by a plus sign on the fi--gure 1), because it contains only one page written in principle eg beforehand for the life of the ring, which contains the confidential identification number of its holder author, written when the account was created. Note that the confidential code is designed, in a manner not represented, ~ açon as it represents the wearer of the ring as well than his bank.

As they arrive, the impulses of clock detect in the selected page of the memory module the value of the different bits present on the considered output from the most significant bit to the most significant bit which are transmitted in series through the coupling ge (104) to the adder-subtractor (31), which displays by counting in binary form and in parallel, a number x, which is sent to the input of a comparator (30), on the other inputs this comparator (30) is already displayed in the same form a number y, which has been transcoded in a manner not shown in from the identification number previously dialed on: ' decimal keyboard (31) by the wearer of the ring, in the event of a tie of x and y, the comparator (30) sends through the AND gate (85) a level 1 at the "preset" input of the flip-flop (42) which cule, applying by its output a logic level 1 at the input of the OR gate (41), which maintains the clock 33 a-p When the timer (28) stops.

(82) of ~ açon to preserve the addressing of the memory (50) and per-put the writing of a new credit possibly requested by the wearer of the ring on said blank page.
- Writing of the new credit:
The same logic level 1 of zero detection, cross sant the OR gate (108) advances the counter (~ 7) by one notch, and, consequently, places the multiplexer (46) on its po ~ ition en-~ 0 very noted ~ 1) and the d ~ encoder (48) in its no-out position t ~ e 1, which keeps the subtractor adder (49) in posi-positive counting by the presence of a logic level 1 9 on the other door entrance or (52), this same logic level 1 is transmitted ~ through the coupling ~ 57) to the write input lec-ture of the memory of cr ~ dit (50), which places the latter in position ~ writing by removing the address ~ age at the level of latche ~ ~ 2), opening the solid reading contacts ~ 3) and removing blocked of the door AND ~ 7). Entering information in mode s ~ rie in the page intended for atre written then takes place through to the multiplexer ~ 113) (Figure 1), both towards the lam ~ credit memory via the coupling ~ 120) than the sequential adder subtractor (49) through the multi-plexer (4 ~), the multiplexer (113) being controlled by the counter (115) activated by the general clock, the value of the amount to be credited is therefore entered on the first blank page from the credit memory (50) and a30ute to the sum previously displayed on the display member ~ e (69) through the counter, 16-bit counter of the sequential adder subtractor (49).
The end of the written page is detected by the AND gate (59) whose the two inputs are both at a logical level 1 at this instant, the first input being the output marked 1 from the decoder (48), the second being the highest weight output of the comp-tor (115) through the descending monostable (140) whose role is precisely to detect the passage of the counter ~ 115) of the tat n ~ 7 in state n ~ Ø When reading and writing.
in the memory (50) of the new credit has ended, the value corresponding is deleted not shown, by the lec-credit voucher ~ (114) by the appearance on its entry no-tee E of a logi ~ ue 1 level transmitted by the driver (93). The output of the AND gate (59), brought to level lo ~ ique 1, resets then zero the credit and debit memories via the OR gate ~ 60) and coupling ~ 45), and, via the OR gate ~ 108), advances the counter ~ 47).
- Reading of previous debits:

The first page blank in the flow memory is detected by the AND gate (109) by the presence at the output of the sequencing adder subtractor tiel (49) of a logic level 1 on its DZ output, it should be noted that at the moment this information appears, the outputs of the a (l-sequential subtractor (49) are in digital state risk in stable binary representation, corresponding to the opera-tion:
X = (sum of previous credits) + (new credit) -(sum of previous debits) this value X being necessarily positive, even in: the cases where the new credit is zero: assuming a previous balance zero laughter and writing a new zero credit, the value of X would obviously also be zero, which constitutes a case limit.
The value of the sum intended to be debited, by the distributor, composed before the introduction of the ring dan ~ the distributor by the wearer of this ~ last on the keyboard (63) in decimal representation, is compared, under its binary form Y, at X pax the binary comparator (110), at the mo-ment where the output not ~ e 3 of the ~ encoder ~ 8) s ~ ta ~ at lo ~ i ~ uo 1, this occurs during the last ba ~ culement of the comp-tor 47 caused by the arrival of a logic level 1 at the output of door 109 ~ cross ~ door 108, the comparison of X and of Y creates a loyal level equal to 1 on the single exit from the parateur 110 if and ~ only ~ i X e ~ t greater than Y, at this time, the counter 115 which controls the successive input states of the multiplexer 116 ~ both reset to zero when the counter 47 ..

- Written of the new flow.
In ef ~ and, the multiplexer 46 being in its position input marked 3 is in communication with the memory of flow 51 via coupling 124 for writing a new flow whose value is counted simultaneously in the same way as previously by the sequential adder subtractor 49 in stable and subtracted binary representation in the af organ file 69. It should be noted that the ascending monostable 81 plays the same role for the flow memory 51 that he played for the credit memory 50, i.e. the memory entry does well on the first blank page detected, not on the next which is also a blank page. On the other hand, the output noted 3 from decoder 48 being at logic level 1 place well the flow memory 51 in the write position during this last phase of operation of the device via coupling ' 123, at the end of this phase, a general stop order is issued qué par basGulement rocker JK 42 by the presence of a ni-logic calf 1 on its clear input through door 0l1 86 con-following the unlocking of the door ET 111, itself made pass-health by the presence at its entry of a positive impulse is-sue from the exit not ~ e 0 of the descending monostable 140 a ~ issant in the same way as at the end of writing in the memory; moire 50 new credit ~ said ~ The operation of ~ delivery of tickets, not represented, passes at the same time as that of registration of the new d ~ bit dan ~ the memory of d ~ bit Sl, up to the Jomme whose amount has been previously registered decimal position by the wearer of the hague thanks to the keyboard 63 and te ~ t ~ as we saw earlier.

The payer card 201 includes a programmable memory 202 of the semiconductor type associated with control circuits of and coupling means 203 (in particular in the form a comb of male conductors). This card contains moire: the payer's identification data (in particular his secret code, bank account number), list of various its credit operations, the list of the various operations of flow, etc.
The specific device 204 located at the point of sale comprises coupling means 205 (in particular in the form of a comb of female conductors) intended to receive the coupling means 203 of the card. ~ e specific device 204 further comprises reading means 206 and means in ~ cription 207 (otherwise called ~ s pro ~ rammeuxs de m ~ moire); ~

command3 allowing data to be entered into the card before appearing, including the amount of the purchase made. The ~ ture 206 means are also connected to a keyboard command 211 associated with an identi ~ -ication comparator 212, these means are intended, on the one hand, to compare the ~ onnées of iden-confidential tification of the payer (appearing on his ~ arte) at confidential code entered directly by the latter into the specific device by means of an input device 211 (for example a control keyboard) and, on the other hand, to authorize the implementation of other means of the specific device in the event positive comparison of identification data and code con ~ identiel.

It will be noted that some of the means described in connection with c ~ tt ~ particular banking application of the system according to the invention tlon are not indi9pen9ables ~ eu as part of this applica-particular banking tlon. Under a ~ simpli ~ iee, the sys-t ~ me general trans ~ er of data that can be extracted from this ~ variants of particular embodiments is represented on -, -. , -, :: ,,,! '' ~ 060582 Figure 5 sui ~ ante. The bodies and means identical to those previously described bear the same references. This sys-teme is composed:
- on the one hand, a plurality of specific devices -independent recording ques distributed in geographic locations phically defined ~ only one 204a has been represented on the fi ~ ure 5) - on the other hand, a plurality of writing devices independent distributed in geographically defined places (a only 204b has been shown in Figure 5) - finally, a plurality of portable electronic objects (only one 201 has been represented in FIG. 5).
The portable object includes:
- ~ e memory 202 associated with a control circuit (202 a), having programmable recording sections of irreversible: preferably, this memory is a memory-dead non-powered semiconductor type, preferably ~ also, this memory is incorporated in an inaccessible way inside said portable object, - deQ coupling means 203 for coupling;
~ will temporarily the portati object ~ with the dispositi ~ spé
registration form 204a.
The specific device of registration comprises:
a means 206 for reading the content of the memory of the portable object when the latter is coupled with the device recording time, a means of recording 20 ~ of the content of the memory-r ~ of the portable object interconnect ~ with said reading means ~ 06 ~; ~
The writing di ~ positi ~ 204b includes a means of ins-cry 207 allowing to write data in the memory programmable of the portable object when the latter is coupled - 27 _ , ~. ,,,. . ; ', 106 ~ S8Z
to the writing device by means of the means of plement 203 and 205. A control keyboard 210 connected to the means of registration 207 makes it possible to introduce into the card the data to be included.
Note that the writing devices 204b are not essential only in the case where the system is designed to tran ~
to store data in the memory of the portable object: likewise it is only in this case that it is necessary to provide a memory 202 having program recording sections wheat or reprogrammable.
Preferably, for certain variant embodiments, as shown in FIG. 6, the devices for registration and writing are interconnected and associated in the same specific device 204.
We will now describe another variant of realization.
tion of the transfer system with reference to Figure 7 which shows the particular structure of the recording medium according to the invention.
We recognize on this ~ i ~ ure most of the organs d ~ crits while re ~ erating in Figure 5, they bear the m ~ my ref-rences, namely: the customer card 201, the disposition of writing 204b, the 2Q4a recording device, etc. In the case of this vari ~ nte of realization according to the invention the means of en-registration 208 is composed of the following bodies:
- a paxt. a portable object ind ~ for 219 (for oxompl0 a card) possibly containing a dead memory programmable 218 associated with a control circuit 218a and connected t ~ ~ dQs coupling means 217, - on the other hand, in the specific arrangement of 30 registration 204a), registration means 215 connected to reading means 206 and coupling means 216 (these coupling means 216 are intended to be ~ coupled to coupling means 217 of the card 219). The means of cription are intended to write in the memory of the card 219 the data read by the reading means 206 in the memory 202 of map 201.
Thanks to this second card it becomes again pos-likely to store in an easily transportable form all or part of the data contained in card 201 and transferred to recording devices 204a. This 219 card can tower be read in another device comprising means for 10 reading, another recording device for example. The - :
writing device 204b whose role is essential only for some applications, allows to register new data born either in card 1 (when it has a memory programmable with recording sections), either in card 219; this writing device can be placed anywhere suitable law where writing is to be done.
It is clear that the recording means 208 de-referenced in Figures 4 and 6 can be performed as just described with regard to the variant of realization tion represented ~ e in Figure 7. In particular the device204 (described with reference to ~ fi ~ ure ~) installed at the com-bottoming may include such a means of registration ~ rement 208. Thus the merchant distributes a merchant card on which is automatically registered the bank account number of the customer ent and the amount of the purchase. The trading cards play the rale of a virtual connection between the point of sale and the bank: ~ each round trip between the point of sale and the bank. the latter (for example by means of a tif reading associated with a central computer) captures the content naked of this memory, is paid by the banks of different pay the amount of the various purchases and credit the merchant account. Moreover. new data may be available ~ 9 10 ~ 058; ~
reported in the bank's merchant card to the point for example: the updated list of card numbers customers subject to bank opposition. It is therefore possible thanks to this system of customer cards and rewarding to exchange data without telephone connections and computer language between customers and geographic traders phically dispersed and towards a central organism: a bank.
We will now describe Figure 8 which represents a more general transaction system, all cards being i-and the distinction between "client" and "con ~ lerrant" é-both deleted.
The apparatus 230 here comprises two inputs 231 and 232 for cards A and B, an amount selector 233 (for example "coding wheels"), as well as an operation selector 234 per-putting to choose one or the other of the following operations:
- A pays B
- A is paid by B
The transaction takes place if the two parties push in same time on buttons 235 and 236, in this case, door 237 is made conductive, activating the start conductor 238.
The device includes ~ possibly two identical keyboards 239 and 240 used to identify card holders A
~ t B.
Such an appax ~ it, designed so ~ ~ be inviolable. is install ~ in any place where a transaction must be carried out, e ~ thus allows the removal of any cash. Each card owner, proving ownership of a card a lot of money (e.g. automatic salary transfer) ple), is done. beforehand, "c ~ arger" his card of said amount money, for example in a bank. The card is then "d ~ charg ~ e" little by little, as it spends by means of machines 230. If, on the contrary, it receives on its : ~ 060582 card more money than it spends it can in the same way "empty" his card at the bank, thus crediting his account (case of a proxy, for example).
Other types of data than digital can evi-How to be exchanged using such a card system: no-many alphanumeric data for example in the context an individual health record or, for example, again in the part of a point surveillance system (each point being ~.
equipped with a memory reader / programmer).
