PCB fabrication instructions: The board has no silkscreen printing, it's a regular white board. Stickers need to be applied to the board, then glue is applied .
 
 Materials: 5*8mm chip, 0603 SMD LED, 100Ω SMD resistor, AB resin glue, cat head sticker.
 
1. COB chip: Honghe IoT Technology (stick) - great chip (https://m.tb.cn/h.5mLnZok) 
2. 0603 SMD LED: TENNIO Electronic Components - eight colors
3. SMD resistor: Qisheng Electronic Technology - 100R
 
4. AB resin glue: Beinu flagship store - 100g makes dozens (do not use UV glue, the finished product will have a plastic feel)
 
5. Cat head sticker: Matte PP synthetic self-adhesive sticker (Printer required; PSD files of the images are attached. If you don't have a printer, contact a print shop.)
We don't do color screen printing because we don't want to waste money on such a small thing, and we feel the effect of color screen printing with epoxy coating might not be very good.
 
 
M1 Card: Sector 0 cannot be modified; other sectors can be repeatedly erased and rewritten. The elevator cards and access control cards we use are M1 cards, not copy cards. UID Card: Ordinary copy card; all sectors can be repeatedly erased and rewritten. Mainly used for IC card copying; it will fail when encountering a card reader with a firewall. CUID Card: Erasable and anti-blocking copy card; all sectors can be repeatedly erased and rewritten. Used when UID card copying is ineffective; it can bypass firewalls. FUID Card: Im erasable and anti-blocking copy card; this card's characteristic is that sector 0 can only be written once. After writing once, it becomes an M1 card. Used when CUID copying is ineffective; it can bypass firewalls. UFUID Card: Advanced copy card; can be understood as a combination of UID and FUID. It requires a card sealing operation; without sealing, it's a UID card; after sealing, it becomes an M1 card.
