摘要

Method for secure exchange of data in service or product transactions involving a user, a supplier and a service provider. The user supplies an encrypted token to a supplier containing personal information necessary for carrying out a chosen transaction. The supplier sends the token to a service provider who is able to decrypt and validate it. The user generates the encrypted token using an electronic device. An Independent claim is made for a device enabling the secure exchange of transaction information by allowing a user to select information contained in the device relevant to the transaction and to generate an encrypted electronic token from the given information. The tokens can be created using a PC, PDA or mobile phone and an appropriate read-write device.
