An asset manager is struggling with the best way to reduce the time required to perform asset location activities in a large warehouse. A project manager indicated that RFID might be a valid…

Passive RFID tags harvest power entirely from the reader's electromagnetic field, leaving virtually no energy budget for cryptographic processing such as AES or other symmetric encryption algorithms. Even active RFID tags, while battery-powered, use microcontrollers optimized for minimal power consumption and limited instruction sets that are not well-suited to real-time encryption of transmitted data. Current RFID standards such as EPC Gen 2 provide only basic password protection and access control, not full in-transit data encryption, making this requirement extremely difficult to satisfy with standard RFID hardware.

Environmental sensors such as temperature, humidity, and shock detectors are commercially available and routinely integrated into active RFID tags for cold-chain and asset condition monitoring.

Real-time location tracking of assets moving through a facility is a primary and well-supported use case for active RFID systems using multiple fixed reader antennas and time-difference-of-arrival techniques.

Assigning a unique identifier - such as an Electronic Product Code - to every RFID tag is the foundational and most basic capability of all RFID systems and requires no special hardware or configuration.
