RFID individually identifiable

Researchers have designed a system capable of simultaneously measuring hundreds of radio frequency identification (RFID) tags and rapidly testing new RFID tag prototypes, says ScienceDaily.

The research, funded by the National Science Foundation and conducted with former graduate student Anil Rohatgi and current graduate student Joshua Griffin, was presented in April at the IEEE International Conference on RFID.

The system includes three parts, a transmitter, receiver and emulator. The emulator simulates the activity of an integrated circuit. The transmitter sends a radio signal to the antenna. By attaching the emulator to an antenna, a unique spread spectrum signal is transmitted to the receiver.

LXE has introduced the 8650 Bluetooth Ring Scanner for use by mobile workers in a supply-chain environment, says ThomasNet.

The small, lightweight 8650 ring scanner rests on the finger, with the Bluetooth module worn comfortably on the back of the hand or the wrist.

The Bluetooth module pairs with any Bluetooth-enabled handheld, wearable, fixed-station or vehicle-mount computer and reliably transmits critical data from up to 30 feet away. This gives the operator the unprecedented freedom of movement necessary to perform bar code reading tasks quickly and in comfort.

Pune and Mumbai will be among the first cities in the state to have biometric bar-coded ration cards, says expressIndia.com.

These laminated cards will be issued soon to every household by the Food and Civil Supplies Department in a bid to ensure transparency and accountability in the public distribution system.

After the central government began drives to check hoarding of food grains and pilferage last month, the state government has gone for a tie-up with Spanco Telesystems and Solutions, a Mumbai-based company, to overhaul the operation. The company will have a target of issuing 18 000 000 laminated ration cards in the state.
