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.

An electronic payment method representative of credits in a memory comprising the steps of: writing in the memory a first set of 1 bits into a first zone denominated as a payment zone and an identical set of 1 bits in a second zone denominated as a reloading zone, said first and second zones having each a first bit and a last bit, with bits having a rank denominated from a first rank for the first bit to a last rank for the last bit, writing in said reloading zone a 0 in place of a 1, for obtaining an end point indicated as a first stop-bit, said first stop-bit having a given rank, a first counting step for a first payment operation, of a first amount in said payment zone from said first bit an amount of bits equal to 1, to a second bit having a second rank, equal to the rank of said first bit plus a number of bits indicative of said first amount, checking whether said second rank of said second bit is not larger than said rank of said first stop-bit, and if so changing said second bit from 1 to 0, a second counting step for a second payment operation, of a second amount, in said payment zone, from said second bit, which has been set equal to 0 after said first payment operation, a second amount of bits equal to 1, which gives a third bit having a third rank, checking whether said third rank of said third bit is not larger than said rank of said stop-bit, and if so changing said third bit from a 1 to 0, and repeating said second counting step until said rank of said stop-bit is exceeded by the count.
