Five-card switching PCB IC card

Compared with the previous single-card version and three-card version , this time the number of cards has been pushed to a new level, with a total of five cards! And the content of the silk screen has also been changed, from the two-spined salamander paper man before to a bunch of high-looking but useless things that are the favorite of science and engineering students (?), but the overall look has become It's more sophisticated, and it's easier to pretend.

Points to note in this project:

1. A common question, the chip of the card uses UID or CUID or the chip removed from the original card, regardless of the positive and negative poles, just solder them on. If you don’t like it, you can use something to cover the chip slot;
2. When card proofing, choose 0.8mm;
3. The switch for switching cards uses a five-way switch, which is compatible with 7.5*7.5*5mm and 7.5*7.5*6mm, and is also compatible with versions with positioning posts and fixed pads;
4. The five-way switch is relatively tall, so please be careful when using it;
5. It is not necessary to solder all five chips, as long as you can tell which card is which;
6. The silk screen can be changed by yourself, but it is best not to change the shape and coil;
