Have you ever heard of MiFare? Basically it is a contactess smart cards system, and is being trademark by NXP Semiconductors. You might also see some calling it as NFC (Near Field Communication). We are carrying the MiFare ISO14443A Classic 1K or 4K card reader/writer – CR038A.

CR038A is able to read and also write data from/to MiFare ISO14443A card. Antenna is build in the board, so no external antenna is needed. Just connect 5V and UART from computer or microcontroller, you are ready to get your MiFare project working. CR038A communicates with host (computer or microcontroller) via simple UART interface, default setting are 19200 bps, 8-N-1. It is compatible with the MiFare Card (ISO14443A, 1K Classic) that we carry.

The host (Computer or Microcontroller) send command in package to CR038A for certain actions(Read, Write, Change Key, value increment/decrement, etc) and get response from CR038A. Please read through the User’s Manual and examples before use it.
