How NFC tags are mapped to MIME types and URIs. Before you begin writing your NFC applications, it is important to understand the different types of NFC tags, how the tag dispatch system parses NFC tags, and the special work that the tag dispatch system does when it detects an NDEF message.The record type field is a variable length field after ID length field (or after the payload length field if the IL flag is false).

The UID is also an important part of NFC security and anti-cloning . 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 .
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.Before you begin writing your NFC applications, it is important to understand the different types of NFC tags, how the tag dispatch system parses NFC tags, and the special work that the tag dispatch system does when it detects an NDEF message. A UID is a hexadecimal identification number consisting of letters and numbers, 7 bytes in size. The UID is unique worldwide, read-only and can be read by most NFC devices and all NFC-enabled smartphones.
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. The latest addition to the NFC Forum tag Types. These tags operate under a slightly different standard ISO/IEC 15693 and include NXP's ICODE SLIX tags. UID / Unique ID. 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.
