The biggest advantage of Encrypted PIN Pad
This ensures that online transmission of passwords takes the form of encrypted text. The EPP terminals themselves can implement various algorithms such as DES, PINBLOCK, MAC and so on.
Pre-installed DES algorithm, MAC algorithm, PINBLOCK operation, the user-selectable National Encryption Board Encryption chip contains key management procedures, the most simple terminal to achieve key management to prevent the key being stolen in the process of setting. The key is stored internally by encryption means, with no key inquiry path, keys and related important data will be automatically destroyed when the terminal is forced disassembly.
