3. Support type A card (including CPU card) and type B card (including ID card).
4. Detect the card reading distance <= 4cm, the specific distance of each card is different.
5. Module size: 41mm*51mm*1.6mm.
INTRODUCTION TO DEMO
The power input in the figure is connected to the 5V power supply (red positive black negative) module to work. The card can be recognized near the coil on the back.
The indicator light 1 lights up: the card is detected, but the identification of the card type fails.
Indicator 2 lights up: A card is detected.
The indicator light 3 lights up to indicate that the B card is detected.
