 | What is NFC?NFC (near field communication) is a wireless technology which allows for the transfer of data such astext or numbers between two NFC enabled devices.NFC products include NFC cards,passive NFC tag. Examples of passive NFC tags are NFC inlays,NFC stickers, NFC wristbands and other converted NFC products.NFC tags are very similar to a USB stick, except that they don’t have to beplugged into a PC to transfer data. There is no battery inside of NFC tags.They all have an integrated circuit (IC) and antennae inside of them.Data is transferred via this antennae. Metal Isolated NFC tag can work on metal surface,but normal nfc tags can not work.The anti metal layer prevent the tags from disturbing on metal.Ntag213 is the most widely used chip.Other chips are available.
