NFC (near field communication) is a wireless technology which allows for the transfer of data such as text or numbers between two NFC enabled devices. NFC tags contain small microchips with little antennas which can store a small amount of information for transfer to another NFC device, such as a mobile phone.
There’s a whole set of different data types you can store on an NFC tag. The actual amount of data varies depending on the type of NFC tag used – different tags have different memory capacities. For example, you may choose to store a URL (web address) or a telephone number. A standard ‘Ultralight’ chip NFC tag can store a URL of around 41 characters, whereas the newer NTAG213 chip NFC tag can store a URL of around 132 characters.
Right now, almost all mobile smart phones support NFC and the vast majority excluding Apple’s iPhone can both read and encode tags. NFC.Today suggest that you use an Android still for encoding tags but there’s some good Apps available now on the Windows phone. We run a list of NFC enabled phones.
