Process for electronic payment using a memory

摘要

Electronic payment method wherein a memory is used with two zones of equal capacity, a payment zone and a reloading zone. A stop-bit equal to "0" is written in the payment zone. A first payment of a certain amount is obtained by counting an amount equal to the payment of "1's" in the payment zone starting from the first bit in the memory. A "0" is written accordingly. A second payment of any other amount is obtained by counting another amount of "1's" equal to the new payment starting from the preceeding "0" and a "0" is written and so on until the rank of the bit to be written as "0" in the payment zone overshoots the rank of the stop-bit in the reloading zone. For a reloading operation a "0" is written in the reloading zone for all bits having the same rank as the "0" bits in the payment zone and a new stop-bit is determined and this is set equal to "0" by writing in the reloading zone.
