 1. NFC tag UID is represented as a bytestream with the MSB being the first byte in the bytestream.
    * **Important:** Various apps/readers report these UIDs in various byte orders, and sometimes as hex strings instead of bytestreams. For NFCV, the UID MUST be a 8 bytes long bytestream with `0xE0` as the **first** byte (SLIX2 then follows with `0x04, 0x01`).
