Patent attributes
A magnetic field induction coupled RFID system for scanning and reading at least one object having an RFID tag or inlay label device attached or embedded therein to impart a unique identity to each of the objects. The RFID tag has two distinct modes of air interface protocols operating in the same frequency band (e.g., HF band), such that the tag is capable of being read at close proximity range by a device utilizing a command-and-control protocol, such as an NFC-protocol compatible smartphone or similarly functioning device, and alternatively by an RFID reader utilizing a different protocol capable of supporting efficient high-speed anti-collision features for enabling fast inventorying at item level of retail store items, warehousing, customs and logistics operations over considerably greater interrogation distances. The passive RFID can further include a third mode of air interface protocol operating in a different (second), e.g., UHF, frequency band, such as EPCGlobal Class-1 Generation-2 conforming protocol, or a commandless asynchronous protocol operating at UHF.
