For the past decade, RFID has been largely relegated to a fairly unintelligent technology.
Initial applications called for very inexpensive devices that could be deployed in great numbers and without installing much infrastructure. There were advanced applications, of course, but they were definitely in the minority.
RFID is now a more sophisticated. Information from RFID smart cards and tags can be relayed via the IP network to corporate databases. Corporations use the information to implement just-in-time inventories, schedule promotions and special sales and generally make the supply chain more efficient.
An excellent example of RFID's new sophistication is the chipset from G2 Microsystems that includes both RFID for near-field communication and IEEE 802.11 so the information can be sent wirelessly to a central database.
The synergy between RFID and Wi Fi is just the beginning. We will soon be seeing RFID/ZigBee, RFID/NFC, and RFID/Bluetooth technology combinations. Stay tuned to WirelessNetDesignline to stay up to date on the latest hybrid RFID developments.
