ABSTRACT:
The present invention discloses a radio frequency (RF) reader grid and method for facilitating transactions. The RF reader grid includes a transponder, a RFID reader, and a host RFID reader in communication with a merchant system. The secondary and host RFID readers communicate with one another via wireless, RF frequencies. The present invention also discloses a wireless grid that comprises non-radio frequency readers, such as magnetic stripe readers. In addition, a method for using a secondary RFID reader to perform a transaction is disclosed. The method includes the steps of initializing the secondary RFID reader, communication transaction information using the secondary RFID reader and processing the transaction information using a host RFID reader.
