Multiple radio frequency network node RFID tag

Abstract

In embodiments of the present invention improved capabilities are described for a Radio Frequency ID (RFID) tag that contains multiple Radio Frequency (RF) network nodes that provide enhanced memory capabilities, redundant functionality, and multiple frequency capabilities to the RFID tag using an inter-RF network node communication connection. The inter-RF network node communication may allow the coordination of RFID tag memory and functionality.

AI Technical Summary

Benefits of technology

[0010]Coordination may include accessing combined memory. Coordination facilitates redundancy among RF network nodes. Coordination facilitates data encryption. Coordination may be according to a network topology among the RF network nodes. The network topology may be a ring network topology a mesh network topology, a serial topology, a packet-based network topology, or the like.

[0215]The card may be a debit card. Items may be automatically purchased with the debit card using a reader. The debit card may provide automatic identification of a user.

[0216]The card may be a smart card. Items may be automatically purchased with the smart card using a reader. The smart card may provide automatic identification of a user.

[0217]The card may be an ATM card. Items may be automatically purchased with the ATM card using a reader. The ATM card may provide automatic identification of a user.

Problems solved by technology

However, current RFID tags suffer from performance problems.

Passive tags, while not requiring a local power source, suffer from low bandwidth and high failure rates in data transmission.

Active tags, while performing better than passive tags, are much more expensive and require a power source.

The vehicle may be denied access if the vehicle failed inspection.
