InkSure Technologies announced it has been awarded two key US patents related to the firm's ongoing development of chipless radio frequency tags that can be printed on a product. The company hopes to drive the cost of RFID tags down to less than one cent by using special ink. Analysts have blamed the high cost of RFID tags as the main bottleneck preventing its wider use by industry. While RFID technology provides product & logistic information, current RFID applications require that relatively expensive chips be imbedded in the ID tags, making item-level tagging impractical for most products. "If silicon chips were cheaper, they would be ideal for use in RFID tags", said Inksure. "They are versatile & robust, can be made in read-only/read-write versions, can store large amounts of data, transfer it rapidly & be designed to do independent processing."
