RFID Labels & Tags: What are the Advantages of RFID Tags?
Advantages of passive RFID tags are typically compared to alternative technologies like barcode or QR-code.
The main advantages compared to other technologies are:
Line of sight is not required to read the tags; they may be embedded or dirty and still function correctly
Supports read/write of data as opposed to read-only
Large memory (up to 32KB)
Optional cryptographic or password-based security
Long reading distance of several m/ft (UHF)
Ability to read multiple tags at once, e.g. an entire pallet of goods
