Researchers Aim to Slash Cost of RFID Readers

Shopping carts that scan purchases and total up the bill may soon become reality as a result of research making radio frequency identification technology more accessible, a published report said on Tuesday. Researchers at the Institute of Microelectronics said their work could cut the cost of each RFID reader from $1,000 to $100. They have also reduced the size of the readers from a small notebook computer to that of a credit card, according to details of the innovation.
