Electronic Business: TI’s RFID Technology makes wireless watch tick

Mark Long reports on TI’s involvement in creating the Timex-built wireless wrist-watches for the ExxonMobil Speedpass Network.

When Speedpass-enabled customers arrive a the McDonald’s drive-thru window, they simply order their food from the menu board, drive on to the payment window and wave their RFID-equipped wristwatches or key chains at the Speedpass reader. The reader/antenna then passes that information onto the appropriate value added network to verify the customer’s profile and credit information. Upon authentication, the Golden Arches light up to indicate that the tag is read. The system then automatically bills purchases to the credit/check card of the customer’s choice, prints a receipt, and the customer is on his way. There are no extra fees when using this method of payment.
