Background|
USB-Key is the online banking user ID. It is an intelligent storage device which can be used to store banking certificate. With the CPU in the chip, it can do digital signature and signature verification. It can be inserted in the computer's USB port to verify the customers’ identity, and encrypts the transactions and customer information. The series of USB-Key chips provided by Tongfang Microelectronics Company meet various demands in the online banking market.
Features of Product||
- High-performance, Low-power 8051-compatible microcontroller
