How to identify the chip manufacturer based on the original TID code
How to identify the chip manufacturer based on the original TID code
UHF tag memory is divided into 4 zones
Reserved area: stores Kill Password and Access.
EPC area: stores EPC numbers, etc.
TID area: stores the tag identification number, each TID number should be unique.
User area: stores user-defined data.
Regional Name
District Name
Capacity
Position
Bit is bit, byte is byte, 1byte = 8bit, 1 word (word) = 2 bytes (byte)
A Chinese character accounts for 2 bytes, two bytes of a Chinese character
Reserved (0-4) contains 4 characters, the first 2 characters are the inactivation password and the last 2 characters are the access password. Changing the access and inactivation passwords requires a lockout to achieve the effect.
There is a TID number (6C protocol) or UID number (6B protocol) in each UHF tag chip. We know that the TID / UID numbers are only readable and unchangeable. TID / UID numbers are stored by the label manufacturer to set up the ID number, which is unified by the RFID international standard organization allocation. Its definition is similar to our ID card number or cell phone number, such as ID card number through the identification of a good definition of the front part of the number, you can know that a person is a province or region of what city or county of the people. UHF ID number also has the same function, through the identification of ID number you can know which chip is which brand of the company's production of which model of the chip.
The following is a list of code cross-reference tables for various manufacturers' chip models for your reference
6C Series: Judge the chip by the first 8 bits of the TID.
