Key words:
The 4101 chip is a special chip for ID card, with a working frequency of 125KHz. The biggest difference from common ID cards is that the number can be customized and postponed, while common ID card numbers are garbled and cannot be postponed. Data can be read by common ID card readers. Note: Different ID card readers may have different formats. Generally, ID card readers use 8H10D format to read data.

Anti-copy ID chip can be encrypted
4102 chip is a low frequency 125KHZ RFID chip. The embedded self-developed OTP storage unit has a huge cost advantage compared with the traditional OTP process. It adopts the technology that can be written wirelessly. Compared with the laser OTP technology, it has a lower bit rate and can provide continuous codes. The 4102 chip adopts encryptable wireless writing technology to ensure the security and traceability of the application. In addition, the on-chip password protection function provides application support under special security requirements.

External Resonant Inductor Matching and Operating Frequency
The standard MIM capacitor is embedded in the 4102 chip, and the tolerance range is less than 5% in the same batch and less than 10% in different batches. External without any external capacitor, only access to the corresponding frequency of the resonant inductor, you can work properly. The 4102 chip has a built-in 470pF resonant capacitor, which requires an external matching inductor of 3.45mH at an operating frequency of 125KHZ.
Application areas
CONTINUOUS CODE ID
Access control ID with key access
Electronic label
Encrypted access control application
Ordinary access control systems usually only need to pass the ID number verification to enter, and the chip will directly issue the ID number after entering the magnetic field, which will be easily copied, thus bringing security risks. In the encrypted access control system, the 4102 chip will not directly issue the ID number after entering the magnetic field, and will issue the ID number only after the key authentication, thus improving a security level compared with the original access control.

64-bit ID format
Application of encrypted serial ID chip writing system:
First of all, the communication configuration is set up, the specific content is: port number, baud rate, parity bit, data bit and end bit. After the above parameters are configured, the card writing device can be connected.
Secondly, the password of the 4102 chip needs to be set, with a total of 8 digits. Once the password is written to the chip, it cannot be changed. After the password is set, the operation of writing the ID code to the encrypted serial ID chip 4102 can be started.
The system needs to write the ID code for decimal input, while the user code input, once the input is successful, you can write serial ID code operation.
The system in three ways to write code operation: manual input, card number increment, file write.
The above three methods can be set as "continuous card reading/card writing", that is, once this option is selected, the program will automatically write codes in accordance with the preset data, without the need for manual continuous setting, which greatly facilitates the efficiency and time of card writing.
Like passwords, once the ID code is written, it cannot be changed, I .e. the write operation is irreversible.
