Question
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 solution if the asset manager's requirements were supported by current RFID capabilities. Which of the following requirements would be MOST difficult for the asset manager to implement?
Options
- AThe ability to encrypt RFID data in transmission
- BThe ability to integrate environmental sensors into the RFID tag
- CThe ability to track assets in real time as they move throughout the facility
- DThe ability to assign RFID tags a unique identifier

Explanation
Encrypting RFID data in transmission is the most difficult requirement to implement because most RFID tags - especially passive ones - have extremely limited computational power and no onboard battery. They cannot perform cryptographic operations needed for encryption. Standard RFID protocols (like EPC Gen2) do not natively encrypt data in transit. By contrast, integrating environmental sensors (B) is a well-established capability in active RFID tags; real-time tracking (C) is a core use case RFID was designed for; and assigning unique identifiers (D) is a fundamental, built-in feature of all RFID systems (via the Electronic Product Code).
