Chipless RFID tags are radiofrequency identification tags that do not need microchip in the transponder. Several industries such as healthcare and banking are increasingly adopting chipless RFID tags, in order to track products. RFIDs are relatively less expensive since they are not comprised of silicone chips and thus do not require any maintenance. As a result of this, it has been adopted in e-passports and banking cards. Several companies have started adopting chipless RFIDs, owing to its anti-counterfeiting and cost-effectiveness features.
