Short for Near Field Communication, NFC is a widely used technology around us. It's behind daily applications such as access control systems and mobile payment systems. NFC Shield features a highly integrated transceiver module PN532 which handles contactless communication at 13.56MHz. You can read and write a 13.56MHz tag with this shield or implement point-to-point data exchange with two NFC Shields.
In this new version, we assign an independent PCB antenna that can easily stretch out of any enclosure you use, leaving more room for you to design the exterior of your project.
The PCB comes stuck on the shield, but you can easily peel it off.
