The cause of the matter is this: I saw the unboxing video of Chengdu’s admission notice on station b a few days ago, and found that the map PCB inside was so cool. I happened to be studying PCB design at the time, and I thought why Xidian couldn't also build one, so I came up with it.
The size of the card is about 5cmx5cm; there are small holes that can be hung on the keychain; the front is a hand-drawn map of the South Campus drawn by senior students and a PCB map of the South Campus drawn by Amap (the family area is omitted) (possibly Please forgive me if there are any errors); the reverse side is the school logo and NFC functional area, which integrates an NFC antenna (although there is no AR, but I have NFC).
NFC installation method: Weld the corresponding chip at "CUID/M1" under the front of the card.
Chip acquisition method 1: tb buy a cob packaged CUID chip.
Chip acquisition method 2: Tb buys PVC dissolving solution, and with the help of a flashlight, find the chip location in your campus card, cut it out and soak it in the dissolving solution, and wait for the PVC to disperse and the chip to appear. (Note: Any consequences caused by using this method are borne by the operator.)
Campus card simulation method (for experience sharing only, not for illegal purposes):
For students who use the above method 2: No additional operations are required after the welding is completed. The PCB at this time can already be used as a campus card swipe.
For students who use method 1 above: Download MIFARE Classic Tool on a mobile phone that supports NFC, select "Write Tag" in the app, select "Clone UID", open the UID cloning tool, swipe the campus card on the phone, and the app will Automatically obtain the UID, then click "Calculate block 0 and clone UID", place the pcb close to the NFC area of the phone, and wait for the writing to complete.
Note: Since I'm not in school right now, I haven't tested whether it works.
In addition, if you don’t want to use it as a campus card, you can also buy and solder chips such as ntag213/215 and use it as an NFC tag, which can add mobile phone contacts with one click, connect to WiFi with one click, and many other functions. Method: Download NFC-TagWriter-by-NXP on your mobile phone and explore it yourself.
