Radio-frequency Identification (RFID) and Near Field Communication (NFC) is used daily by our customers for cashless payment, access control, social networking and experiential marketing. It's fast, friendly, engaging and reliable, albeit slightly confusing, that's why we're here to help talk it through. If you don't know your RFID card from your NFC tag this information is for you.
To put NFC into context we have to also look at RFID.
What is NFC?
A short-range wireless connectivity technology, it only works when two devices are brought close together, so unlike Bluetooth (BLE), eavesdropping is almost impossible. What's more, it is unique in the way it uses energy. Only one of the two devices needs to be powered
How does NFC work?
NFC-equipped smartphones and other devices can exchange data with each other with a simple tap or wave using a High Frequency (HF) 13.56 MHz radio wave. You may have made a contactless payment with your bank card or even Apple Pay, it's all possible thanks to NFC. Gone are the days of having to scan a barcode or swipe a magnetic stripe, it's all done
What is RFID?
Radio Frequency I
RFID is the technology that underpins NFC and is the process by which items are uniquely identified using radio waves. The waves are created by an antenna which is a linked to a silicon chip. NFC is a specialised subset of RFID. It operates at 13.56 MHz and performs many of the same functions as RFID tags and contactless
Fast, seamless, and easy to use, NFC is now available in hundreds of millions of smartphones, tablets, and other consumer electronics, with new devices arriving almost daily.
Three key differences:
1. NFC is capable of two-way communication and operates in one of three communication modes: Read/Write, Peer-to-Peer (P2P), and Card Emulation
2. NFC is restrained to close proximity communication at typically less than 10cm, hence
3. You can only scan one NFC tag at a time
Which is the best NFC chip?
The most commonly used NFC chip is an NXP Mifare Ultralight EV1, this supersedes the previous version, NXP Mifare Ultralight. The EV1 version offers
1. User memory for Mifare Ultralight EV1 is 48 bytes compared to 144 bytes for
2. NTAG213 is more expensive
3. NTAG213 has a better read range by 1-2cm
Is this RFID technology secure?
There have been many advances over the years in RFID and NFC technology, most in the areas of RFID security and encryption. Early RFID chips, such as NXP Mifare Classic have very low levels of security and can no longer be classified as secure. Since then very secure products that offer , such as MIFARE NXP DESFire lead the way.
What is the NFC Forum?
An organisation formed in January 2005 to develop specifications and test mechanisms that ensure consistent, reliable transactions worldwide across all three modes of NFC. The NFC Forum provides a highly stable framework for extensive application development, seamless interoperable solutions, and security for NFC-enabled transactions.
A key part of the framework governs smartphones with an integrated NFC chip. The guidelines have improved consistency across all handset manufacturers and operating systems. This ensures the same action will occur when an NFC card or NFC enabled media are presented to a smartphone's
Does my phone have NFC?
Yes probably. The majority of handsets are now NFC enabled and can be used to program an NFC tag or for payment. Apple's iPhone X down to iPhone 6 have NFC functionality, mostly used for Apple Pay only. Take a look at the definitive list of NFC enabled phones in use now and on the horizon, courtesy of NFC World.
What is an NFC tag?
NFC tags can be small stickers, which contain a small unpowered NFC chip. Depending on how the tag is programmed, it can change various settings, launch apps and perform certain actions just by holding your phone close to it.
