ISO 14443 Type A tags with 7 byte serial number (similarly for serial numbers of ISO 15693 tags): Each manufacturer is allocated a block of serial numbers (e.g. NXP serial numbers start with 0x04, Infineon with 0x05, etc). Within that block many manufacturers (I'm not sure about all of them) guarantee that they use each serial number only once.Mifare UL has a 7-byte UID. 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-list.c how IDs are retrieved and displayed." The most common NFC tags currently use 7 bytes to store the serial number, providing space for a 14-digit hexadecimal number. The hexadecimal system is converted to a base 16 number system commonly used in computer science where counting is from 0-F (instead of 0-9 as in the commonly known decimal system).
4 Answers. Sorted by: 4. What prevents a 7-byte UID from having uid4, uid5 and uid6 set to zero? Nothing. The format of the UID (as used by MIFARE cards) is defined in ISO/IEC 14443-3. Specifically for MIFARE cards, NXP has (or at least had?) some further allocation logic for 4 byte UIDs, but that's not publicly available.
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 UID cannot be deleted or changed, so that each NFC chip is unmistakably marked.Introduction. This document shows the use of UIDs in contactless smartcard systems. It indicates recommendations about the use of Random ID, the mixed use of 4-byte (single size) and. 7-byte (double size) UIDs in the same system, and it describes the options how to upgrade 4 byte UID systems to use 7 byte UID smart cards.

Cloning a 7-byte UID MFC (Mifare Classic) 1k card and more. This is a little blog about my trials of figuring out how to clone a 7-byte 1k MFC card and more I discovered. I'm not an expert, this is just what I found out. I'm writing it down because I couldn't find a single place where this info was grouped together.NTAGs come with a 7-byte UID, a range of memory sizes, advanced functionality such as originality signature, static or dynamic memory protection, along with AES-128 cryptography for secure authentication schemes. Specialized variants come with electronic opening status detection and passively powered sensing capabilities. Services.NFC Tags. Read Only NFC Chip UID. The NFC chip UID on most NFC chip types is determined by the chip manufacturer, programmed to the NFC chip during manufacturing and is permanently read-only; meaning that it is not possible to change the value of the UID via software. Byte. A number between 0 and 255. Data is stored on NFC Tags in Bytes. Each Byte can store one character, therefore if you store 10 characters, you need 10 Bytes. Card Emulation. A process where an active NFC device (say a mobile phone) will 'pretend' to be a passive NFC tag or card. Chip. See NFC Chip. Clear Sticker (Clear Tag)
