Description
WH-10,1)74CA
TITLE: FINANCIAL TRArdSACTION TERMINAL WITH LIMITED ACCESS
FIELD OF THE INVENTIOrd The present invention relates to financial tran;~action terminals capable of: cooperating with smart cards stored in an accessible part of the access terminal.
In p~~rticular, the application i.s directed to improvements in security of such terminals.
BA KGROUND OF THE INVF;NTION
Miniature smart cards compliant with the GSM 11.11 Standard, are commonly referred to as SIM (Security Identity Module) or SAN! (Secure Access Module) cards.
These=_ devices have the same I/O pad configurations and capabilities as a standard ISO (CNet) smart card. The SIM
or S~~N! cards, because of their small size, can be installed insi~~e a financial transaction terminal for verification, password, registration, billing information or as an electronic purse, whez-e monetary values can be transferred to and from the smart card. Both the SIM and SAM cards have special adapters for attacr.~ment to a circuit board for receiving the card anc~ eler_trically connecting the card with the circuit board. In this way, the circuit board comm~inicates directly with the card which is removable.
The riser, from time to time, may need to replace the SIM or SAM ~~ard and as such, requires access to the acceptors.
For example, these cax-ds can be used as an electronic purse which is replaced by t:he u:~er, when the old one is full.
Financial terminals which are smart card compatible have become increasingly popular for point of sale transactions.
Simi:Larly, debit fund transfer systems are becoming quite common. A single terminal which. is compatible with both systems would be desired.
In a debit system, PIN entry is required as a means to identify the legitimate user. This PIN is protected by encr:~pting the PIN and dat<~ which is received by the unit WH-10, ()74CA
or sEsnt by the unit. In addition to this electronic coding, the common standards, such as INTERAC and VISA, require certain physical security to protect against unauvhorized entry to the unit. Financial transaction terminals for debit card transactions have an electronic switch arrangement which shuts down the unit if the housing of tl:xe financial tram>action terminal is separated exposing the ~=_nclosed circuitry and software.
The debit card. security approach is desirable, howe,;rer, it is also desirable to have a device with SIM or SAM ~~ards for recordal_ of certain information directly in the device while allowing a user access to these cards.
The 1?resent invention combines these two capabilities and whip=_ providing effective security for the financial tran;~action device.
SL~~RY OF THE INVENTION

The terminal 2 has a housing generally shown as 12 which in this case, i~> a two-part casing having a front housing 14 and a back housing 16. Basically, the casing 12 is horizontally split into the t.wo parts and suitable eleci~ronic circuitry arrangements can be provided to alert the i~erminal that the casing has been opened. The front and ~~he back housing are typically mechanically secured and if rf~leased, the terminal detects this release and protects or e.Liminates any critical information.
The back of th.e housing as shown in Figures 2 and 3, has an access port 18 which exposes part of the circuit board 22. SIM or SAM type acceptors 20 and 21 are secured on the circuit board ~:2 within the access port 18. The user, such as a merchant, has ready access to the acceptors and 21 and can insert the appropriate SIM or SAM cards.
A re:Leasable cover 24 protects the access port 18. The SIM
or SAM cards are examples of two of the most common user inserted modules that record information and financial 20 tran:~actions for example. Other modules can be used and the i~erminal is not limited to these particular modules.
The housing 16 includes side walls extending down~Nardly and contacting l:he circuit board 17 to provide a boundary area about the access port 18. In this way, acce:~s is provided to the port, yet access to the rest of the i~erminal is restricted. Critical parts are mounted on the circuit board 22 at a position which is interior to the hous:Lng and preferrabl.y remotely located, relative to the acce:~s port 18.
An electrical switch seal arrangement 28 is prov:Lded, as generally shown in Figures 4 and 5. The back hous:Lng 16, as shown i.n the sectional view of Figure 4, has a series of zebra strip connectors generally shown as 30 in contact with the circuit board 22. The left hand side of the drawing shows two such zebra. strip connectors which mere:Ly provide additic>nal protection. Each zebra strip WH-1G,G74CA
connE~ctor, as illustrated in Figure 5, has alternating conducting and non conducting layers. The spacing of these layers which are extending horizontally is such that they will make contact with opposed terminals 32,33 or 34 provided on the circuit board 22 and these alternating layers separate adjacent terminals by at least one non conducting strip. Each side of the circuit board, adjacent the <~ccess port 18, has a series of logic switches formed by these terminals 32 and terminals 33 or 34. At the left of the circuit board, there are seven logic switches labe:Lled SW1 through SW7. Terminals 34 are connected to the around whereas terminal 33 a.re connected to a 5 volt supp:Ly. The zebra strip connector electrically connect each terminal 32 with oppo:>ed termina.ls 33 or 34. With this arrangement, logic switches SW7, SW5, SW3 and SW1 are shorted to ground. In contrast, the terminals 33 associated with SW2, :>W4 and SW6, are connected to a 5 volt power source. As such, these switches are closed, i.e. the circ»it is live. As c:an be appreciated, different logic pattf~rns of ones (5V) and zeros (ground) can be detected by a processing arrangement 39 on the circuit board. The zebra strip connector is resilient and the pressure of mech<~nically joining t:he two housings is sufficient to ensu=re some compression of the zebra strip connector and a good electrical connection between the terminals 32, and oppo;~ed terminals 33 and 34. If the housing is opened or tampered with, at lea:~t some of the logic switches change status as the circuit will be broken.
Figure 5 under each of t:he zebra strip connectors 30, has a similar switching arrangement 31 and thus, there is multiple switch protection on. each side of the access port with some of the switches being connected to ground and Nome of the switches being connected to 5 volt power.
The :Fact that the zebra strip connectors have a series of conducting and non conducting layers, allows each of the switches to be isolated from the adjacent switch by at least: one non conducting strip and preferrably two non 4AH-10, I)74CA
conducting strips and it also ensures that an effective electrical connection between terminals is provided without the need for precision location of the connectors.
The logic switches defined a logic high, in this case, 5 volts, and a 7_ogic low, i.e., ground. The multiple switches form a code of highs anal lows used to detect a chance in security status of the case.
The additional zebra strip connector shown as 30a in Figure 4 provides enhanced protection. As can be apprf=_ciated, the zebra strip connectors 30 are located immediately adjacent t:he access port and if there is any attempt to pry up the housing adjacent the access port, this action will open or change the logic of at least some of the switches. Once the status of the switches is chanced, the terminal will become inactive and therefore, even if the housing i~~ broken into, the critical information will have been eliminated, or the device rendcsred inactive. Additional zebra strip connectors further away from the access port provide additional protection against unauthorized entry into the casing.
In some cases, it may be desirable to take security action if one switch changes (high security), however, in other cases, the security action. may require two or more switches to change. F~'or example, dropping of a terminal mighty momentarily change the status of one switch and it may he desirable to require change in status of more switches or changes in status for a certain time duration befo._a taking security action. The present arrangement allows for these type~~ of changes in design to customize the :security for a particular application.
Although the security switch arrangement provides protE~ction about the access port, it also provides protE~ction against unauthorized opening of the casing by separating the housings.
LVH-10 , 074CA
The present invention allows the simple formation of terminals on a circuit board to provide switch information or switch logic through a multiple series of swit~~hes using a zebra strip connector having the alternating layers orientated by across the surface of the conn~=_ctor connections. The switches are isolated one from the «ther and it is not necessary to precisely locate the zebr<~ strip connector:>. The separation between the layers is such that any placement of a zebra strip connector in the housing and over t:he terminals will be sufficient to provide the necessary electrical connection and electrical isolation of terminal: on the surface of the circuit board.
The terminal is designed using an outer housing to protEsct the component~~ with a recessed covered access port to a:Llow a user to in=pert or remove certain modules in elect=rical contact with the internal processing circuitry.
Although the access part is within the housing, electrical security sales are provided about the access port. V~lith this arrangement, the security o~f the terminal is uncompromised and the convenience of limited user access is realized.
Although various preferred embodiments of the presf~nt invention have been described herein in detail, it will be appreciated b~~ those skilled in the art, that vari<~tions may be made' thereto without departing from the spirit of the invention or the scope of the appended clairns .
