Most cell phones today contain a SIM card, which can be swapped with the ones developed by SKT to read the radio waves emitted by the tags attached to medical supplies, whiskey and other products to ensure its authenticity.
SK Telecom recently announced the development of a universal subscriber identity module, or USIM, embedded with a 900 megahertz RFID reader.
The RFID reader connects through a 3G or Wi-Fi network and provides information such as the product’s place of origin, delivery destination, and expiration date and also whether the product is genuine.
The technology will be tested by Incheon International Airport’s Air Logistics Management Service starting in August.
The new USIM cards are expected to cost roughly $25 – $35, and is expected to be available to the public in 2011.
