## Description

**FACE-RFID** is a FACES kit compatible panel, with the Radio frequency identification chipset integrated on it.

Same as RFID units,  it is MFRC522-based. The MFRC522 operates in the 13.56MHz frequency band and uses the modulation and demodulation principle to interact with the proximity RF card.
<br>
This unit can realize the function of the card reading and writing device, to identify and record multiple card information, to encode and authority an RF card. With FACES panel, you can have an upgrade level of RFID device with a more complete and enclosed pattern.

>1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.

>2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click **"Burn"** to start burning.

>3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. [Click here to view the driver installation tutorial](en/related_documents/M5Burner#install-usb-driver)
