Description

The principle of card reading: by driving the RFID-RC522 module, identify the ID card ID close to the ID card and then determine whether the ID exists in the database of the word typical, ID is the typical value of the word, if the existence of the verification through, and then print out the corresponding name, and then drive the electromagnetic lock in the same way.

Realized function

1. card registration.

2. username and password registration.

3. card swipe to unlock the electronic lock.

4. User name and password to unlock the electronic lock.

The main hardware Description

RFID Module

This module can be directly loaded into various reader modules. It utilizes a voltage of 3.3V, through the SPI interface with simply a few wires. Directly connected with a CPU motherboard, the module can work in a stable and reliable manner as a distance card reader.

STONE STWI070WT-01 display

The STWI070WT-01 has been conceived as a TFT monitor & Touch controller. It includes a processor, control program, driver, flash memory, RS232/RS422/RS485/TTL/LAN port, Wi-Fi/Bluetooth, touch screen, power supply, etc., so it is a whole display system based on the powerful & easy operating system, which can be controlled by Any MCU.
