| Abstract: | In reality neerly all password input sets are fixed, so that the passwords would be stolen easily. Accordingly, a multi-functional password input set based on STC89C52 microchip is proposed. The working principle is put forward, and the specific hardware design and software design are introduced. The results show that the set has the advantages of convenient use, good security and novel design, and could be applied in variety fields of electronics engineering such as ATM and POS. |
