Abstract
A prior introduction into the memory of a document in a non-validated state, to be acquired by validation, and a function of acquiring the document, independent of the electronic purse function. When it is wished to acquire such a document, the sales terminal and the independent functions of acquisition and electronic payment of the card are put in communication. A document acquisition order is placed, transmitted to the acquisition function by the terminal. Verification of the presence in the card of the document to be validated and its authenticity and a verification of the presence and authenticity of an amount in the purse for the acquisition of a document are organized. If the two verification steps are positive, a simultaneously sending of a global agreement signal to each of the functions is organized in order simultaneously on the one hand to validate the document as an acquired document and on the other hand to debit the purse by the amount of the acquisition.
