At the deficiency of above-mentioned electronic money, the inventor proposes a kind of improvement project, and we are more taken a step forward to the digitizing life.

Summary of the invention the objective of the invention is to propose a kind of design proposal of improving the card form electronic money, make it can independently inquire about and demonstrate surplus, find to pay clearing and correct errors, need not the small change clearing, carry facility, can be widely used in a kind of novel intelligent cassette electronic money of multiple occasion.

The object of the present invention is achieved like this, the development trend of current electronic money is to use noncontact radio frequency induction formula IC-card, its inner main electron device is that an induction antenna coil and one include central microprocessor CPU, electricity is wiped the programmable storage EEPROM of rewriting, random access memory ram, and the integrated circuit modules of the read only memory ROM of curing card operation COS system, carry out the bi-directional digital message exchange by the principle of electromagnetic coupled and the radio frequency induction window on the card reader, radio frequency induction circuit in card reader passes to central microprocessor to signal through modulation-demodulation circuit after receiving again, discern comparison with the information in the storer, if it is identical with the information of agreement, card reader just can be reacted, send this user's of instruction unpack access accounts through microprocessor, the formula of remitting account consumption, for further accomplishing the energy independent displaying, card-type electronic business card or counter and induction type radio-frequency (RF) IC card are combined, utilize the microprocessor of card-type electronic counter or electronic business card inside, controller and storer and lip-deep liquid crystal display and operating key, manufacture the electronic money that can show balanced value in the inquiry, have simultaneously " all-purpose card " function again concurrently, and the usability of possessing primary electron counter or electronic business card, just become a kind of novel electron currency of being convenient to carry, consumption is stolen by other people in the back in order to prevent loss, utilize keyboard on cassette counter or the electronic business card can input the startup password of personal set, and can add the correction of password and rewrite function, become the stored value card of using more.

Further set forth concrete structure of the present invention below in conjunction with accompanying drawing

What appended drawings showed is the front view (FV) of this electric bank-note card

1 LCDs, 2 solar cells, 3 membrane keyboards among the figure

Electronic money in the embodiment accompanying drawing is to make on the basis of electronic business card, the upper left corner is LCDs 1, inside circumference insert along profile the radio frequency induction aerial coil, the radio frequency induction IC module that links to each other with induction antenna on also adding in inside simultaneously, the upper right corner is the energy of solar cell 2 as system.

Press starting switch when consuming, at first demonstrate the amount of money number of inner residue surplus on the liquid crystal display, if electronic money is configured to other non-financial consumption states, then open liquid crystal display by independent display switch, in order to prevent in the strong or not dark occasion of light, the battery powered deficiency of sunlight installs a standby button cell additional in the card, make electric bank-note card can both guarantee under any illumination condition that liquid crystal display is made clearly and show.Before the valuation consumption clearing card is pressed close to the radio frequency induction head of card reader, aerial coil in the card just can receive the signal that sends from card reader, microprocessor and controller are transmitted to card reader to the account number cipher in the storer in blocking, compare with the account number cipher of machine stored, if the password difference is then refused to make a response, if password is identical, then open this user's record keeping book, importing the consumption password code of oneself setting by keyboard by the user then promptly can carry out access and remit account, if it is not right that account book is opened the password code of back input, just can not carry out accessing operation, so just guaranteeing that other people can't remit account to withdraw the money consumes use, the account number cipher and the password code of remitting account can be adjusted change again after correct input, prevent from the passing of time to be found out inefficacy by the people.

The big benefit of another of this kind electronic money is when carrying out the consumption of multiple project, the user can utilize the counter on the card to add up and proofread calculating, examine with attendant's quotation, change the passive situation when having a prescription priced clearing at present, though the consumption amount of money that shows on fee register is two-way usually, the consumer also can see the result that has a prescription priced, if but the valuation personnel have imported a certain wrong in the middle of valuation, the consumer was difficult to perceive at that time, for example food and drink consumption must be consulted the bill of getting afterwards, not as statement in time, correct the valuation mistake, reach as clear as noonday consumption.

The function of this kind electric bank-note card is diversified, switching by keyboard and switch, can start the function menu of inner setting, select respectively financial consumption, sub-district service consumption (parking, body-building, beauty treatment, amusement ...), radio-frequency (RF) IC card opens the door, the function of many " all-purpose cards " such as personal medical information, authentication, Bus Card, makes our consumption of going out convenient more.
