Abstract (en)
[origin: WO9904374A1] The invention provides a secure transaction system including a transponder (100) (tag), point of sale (POS) device (200) and a host network authorization system (300). The transponder and host are arranged to communicate with each other via the point-of-sale device and at least one of the host or transducer authenticates that information received originated from the other, the authentication being based on data available to the host and transponder which data is not available to the point-of-sale device. By employing the invention secure information may be communicated between the transponder and the host via the point-of-sale device without access to the information being possible at the point-of-sale device itself.
