Abstract

A device for the use of and easily portable by an individual, consisting of a main memory, a microprocessor, a keyboard for the control of the microprocessor, etc., and at least one accounting memory and a display. Operation of the keyboard in a pre-determined fashion will cause the microprocessor to transfer one or more units of information from the main memory to at least one accounting memory. The point in time at which this transfer is made directly or indirectly (for example via internal delay circuits) may be determined by the individual. The number of information units to be transferred is determined by operating the keyboard in a certain, preferably combinatory fashion. Each information unit or group of units which is transferred from the main memory to the accounting memory by operating the keyboard in some other, certain, preferably combinatory fashion will either be given a certain address code or will be allocated to a specific accounting memory.

Claims

1. A method for recording financial transactions in a cash-less payment system having a portable device, which includes a main memory and plural accounting memories, and a terminal by which information relating to financial transactions is transferred into at least one of the memories in the portable device, comprising the steps of:

upon the payment of a fee, loading the main memory of the portable device, via the terminal, with units of information corresponding to the amount of the fee;

upon the occurrance of a financial transaction, allocating a number of information units, corresponding to the amount of the transaction, that are stored in the main memory to an accounting memory assigned to the creditor with whom the transaction is made; and

reading the contents of the accounting memories, via the terminal, and providing an indication of the creditors with whom transactions were carried out and the respective amounts of the transactions.

2. The method claim 1 wherein each of the units of information stored in the main memory has an identical value.

3. The method of claim 1 wherein the allocation of information units to an accounting memory comprises transferring the information bits from the main memory to a separate accounting memory.

4. The method of claim 1 wherein the allocation of information units comprises assigning a predetermined address marker to the information units in the main memory.

5. The method of claim 1 wherein the allocation of information units is effected by actuating a keyboard on the portable device at the time of the transaction.

6. The method of claim 1 wherein the allocation of information units is effected by actuating a keyboard on the portable device prior to the transaction to enter a predetermined code which causes the allocation to be automatically made at the time of the transaction.

7. The method of claim 6 wherein the code is displayed on the portable device when the keyboard is actuated.
