Gamma Solutions gives valuable information on the RFID tag.
In general, an RFID tag consists of an application-specific integrated circuit (ASIC) and an antenna that can be mounted on various substrates.
Each element of an RFID tag is selected for optimum efficiency for the application. Physical sizes can range from as small as a thumbnail to as large as a brick.
Intermec’s RFID tag and label product line offers up to 2048 bits of memory and read ranges up to 25 feet, dependent upon the application. The term "tag" and "transponder" are synonymous.
Cost of RFID tags:
Tags can cost as little as 10 cents or as much as $100 depending on the type of tag, the application and the volume of the order.
Generally speaking, finished smart labels that can be applied to cases and pallets typically cost between 10 and 20 cents, depending upon volume. Active tags - those with a battery - can cost far more.
