Infosys has designed and deployed a vehicle access-control system using EPC Gen 2 passive RFID tags. For those hearing the term for the first time, relax. RFID stands for Radio Frequency IDentification. These are small chips or chips embedded on plastic cards that can hold information and pass it on wirelessly to a reader which scans a given area of influence. For more refer to HowStuffWorks and Wikipedia.
What Infosys has done is this. Deploy RFID readers across its multistory car-parks. Employees have been issued RFID tags to be placed against their windscreens. Whenever the employee approaches within 3 meters of the RFID reader, the system reads the information in the RFID tag on the employee's windscreen, authenticates him as a Infosys employee and lets him access to the car park area.
Prior to this being implemented, the employee had to stop over and roll down the wind shield to swipe a RFID card against a card reader that could only read in the vicinity of a few centimeters. This used to result in serpentine queues of cards waiting outside the car park area just waiting to get in. Now the same technology extended has not only helped ease employees' lives but is also getting new orders for the company.
