Campus NFC Card

Overview

This is a campus NFC card. The chip controls the LEDs to blink. There are four 0805 LEDs on the front. They light up when you swipe the card, but they also work normally without the LEDs. You can use your phone to simulate a campus card by attaching a 3*5mm CUID chip. Tips: The CUID chip can only be read and written using a card reader.
