System for controlling access to commercial sites and for securing commercial transactions based on use of a removable data drive and associated removable data disk, so that a chip card reader is not required

摘要

System for securing transactions comprises a plurality of transaction terminals (101), a plurality of removal data supports (100) each containing information for effecting a commercial transaction, a control site (102) and a third party site (10), the various parties being connected by a communication network. The data supports, such as CDs, DVDs, diskettes, PCMCIA cards, etc. have corresponding readers or drives that are not normally used for payments and contain at least an identification element permitting the opening of transaction sessions. Independent claims are made for a data support (100) comprising data that allows commercial transactions to be carried out and a control site (102) for ensuring the security of transactions.
