Method for controlling access to goods or service using mobile telephony for payment authentication in which an authentication code is issued to release the goods that can be used only once to prevent fraud

摘要

Mobile phone (1) communicates with a central unit (5) and a release device (10) for access to goods or services. The phone transmits authentication data to the central unit, and uses the data to carry out authentication of user. If authentication is successful, a user release code (FC) is sent back with which goods or services can be purchased. The release code is altered by the release device (10) after goods release so that it can no longer be used. An Independent claim is made for a system for controlling access and purchasing of goods or services based on a mobile telephony communications system.
