TOKEN FOR SHORT RANGE RF TRANSACTION NOTIFICATION

摘要

A token has an antenna and a short-range RF receiver to receive wireless receive bursts comprising receive protocol overhead and transaction credentials. A parsing circuit selects a subset of the transaction credentials including a duration of an associated transaction. A credentials memory holds at least the subset of the transaction credentials for the duration of the transaction. A display and/or shortrange RF transmitter notifies a transaction notification indicative of the subset of the transaction credentials held in the credentials memory. The short-range RF transmitter transmits wireless transmit bursts in a burst data length shorter than a burst data length of the receive bursts. The wireless receive bursts can have control data and the parsing circuit selects the subset based on instructions in the control data. A display on a vehicle can render the subset of the transaction credentials for the duration of the associated transaction.
