摘要

A payment system for an electronic wallet (16) in the form of a memory card or similar in which the payment of a purchase made in a store is carried out by means of a payment terminal (20) deducting the amount of the purchase made by the electronic wallet holder from the sum remaining in the electronic wallet memory, said payment terminal being connected to a credit card-type banking system. The system comprises an electronic cash unit (14) situated at the venue of the transaction, provided with a read/write device able to read and write in the memory of the electronic wallet and a security module which is used to give an authorization to carry out the transaction, the contents of the memory of the electronic cash unit being increased by a sum equal to the amount of the purchase when the memory of the electronic wallet is read by the read/write device so that the transaction carried out in the store can be processed at the same venue as the transaction.
