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
