Mifare Classic has a 4 or 7-byte UID. FeliCa has a 8-byte ID. ISO14443-4A has a 4, 7 or 11-byte UID. ISO14443-4B has a 4-byte PUPI. Do some tests with nfc-list, you'll see what comes out depending on the used tag. And for code, see code of nfc . A UID is a general property of most tags BUT different tags have different specifications. Some tags have a small UID size and thus UID re-use is likely. Different tags have different length UID's. Some are supposed to be set at the factory but clones allow them to .The NFC chip UID is a manufacturer -supplied, usually read-only, unique identifier for the NFC chip used to uniquely identify an NFC tag in a project’s software systems. The UID is also an important part of NFC security and anti-cloning.How many types of UID exist in contactless RFID card systems? UID standard for Unique IDentifer, which is a common expression defined for RFID IC selection and activation. The standard defines single, double and triple size UIDs which consist of .

In simple terms, the UID is a simple number that is permanently stored in the NFC tag. The most common NFC tags currently use 7 bytes to store the serial number, providing space for a 14-digit hexadecimal number. For that tag, your reader should output one of the following numbers (depending on how properly it is implemented): 123 11136 (using 0x7B 0x2B80, if full UID is considered), 004 52287 (using 0x04 CC3F, if first cascade level is considered), 204 01160 (using 0xCC 0488, if UID is read starting at the wrong end and cascade tag is invalidly .

The NFC chip UID is read by a device from an NFC chip either by reading a specific portion of memory, by calling an NFC chip command or from a software subsystem that performs one of these; which method is used is based on the NFC tag type and NFC chip type. We learn how to read, write, and emulate NFC tags with Arduino and the PN532 reader/writer. NFC is a superset of RFID, which allows us to communicate remotely with active or passive tags, and is widely used in touchless systems.

NFC Tag UID Scan. Each NFC tag that we sell and many of the NFC tags on the market contain an effectively unique seven byte unique ID. Seven bytes equates to 14 hexadecimal characters. A hexadecimal character is a number from 0 to 9 or a letter from A to F. The UID of an NFC tag is typically a 7 byte / 14 character unique number which is set during the chip manufacture and cannot be changed. On some chips, it can be 4 bytes. It can be used to identify an individual chip/tag.
