[Creative PCB] Small Lantern NFC Card 689677z

With the continuous development of mobile payment and Internet technology, more and more people choose not to carry wallets. At this time, ordinary IC cards gradually fail to reflect their original advantages, especially for people who often carry several cards with them. . This project is a portable transformation based on ic card.

       If you directly read the data on the encrypted chip and write it to the card by cracking the encryption algorithm, you will face the following problems:

1. Difficult to crack (most people don’t have special equipment)
2. May face legal issues

        Therefore, here I choose to directly remove the chip in the card.         For those who do not need multiple cards, you can add an NFC chip and write data as business cards, WiFi passwords, payment data, etc. to achieve efficient work.         The NFC chip is NT3H1101W0FHKH.         Just install one NFC chip and uid chip. Each lantern can install two chips!         You can install 2 uid chips, or 2 NFC chips, or 1 NFC chip and 1 uid chip!
