Just tap it!What is NFC?
www.FutureElectronics.com
Card Emulation: • Allows enabled devices to act as smart cards to perform transactions (payment) • Examples: Payment, transport, event ticketing, access
Near Field Communications (NFC) is based on the same technology, but has standardized information packets (NDEF), and additional hardware modes of operation (Reader/Write, Peer-to-Peer and Card Emulation). These new features are intended to make it friendlier to a mass market and mobile applications.
Read/Write Mode: • Allows NFC enabled devices to read information stored on NFC tags • Examples: Warranty registrations, validation of disposables
Peer-to-Peer Mode: • Allows two NFC enabled devices to communicate with each other in an ad-hoc manner to exchange information • Examples: Speakers, routers, configuration of drivers
Each full NFC device can work in all three modes.
Two NFC enabled devices are needed to transmit data: 1. Initiator (or Reader): initiates communication and controls data exchange 2. Target (or Tag): responds to requests from the initiator
HF RFID is a contactless technology operating at 13.56 MHz designed to transfer small amounts of data between two devices in close proximity (typically ~10cm).
This technology is traditionally seen in Building Access Control (Employee Badges & Card Readers) or mass transit ticketing. HF RFID typically consists of two components: a reader that generates the RF field and a passive tag non-volatile memory that gets its energy from the reader. Though the communications protocols are based on ISO standards, the infor-mation stored on the cards is proprietary and encrypted.

• Does your product need to be configured only occasionally and would benefit from a large touch screen?
- See NFC use case: Parametrization and Diagnosis
- Solution to consider: Connected tag IC in combination with an NFC enabled phone as an external user interface
• Does your product have consumables or accessories which need to be identified or authenticated?
- See NFC use case: Identification and Authentication
- Solution to consider: Inlays (Tag ICs for labels) + NFC Reader IC
Tag ICs for labels: NTag 210, NTag 213
Some NFC Discovery Questions to Consider: • Do you use DIP switches or rotary switches to parametrize your product?
- See NFC use case: Parametrization and Diagnosis
- Solution to consider: Connected Tag IC + NFC Frontend IC
Why NFC?
More Intuitive than Bluetooth and Wi-Fi It’s like shaking hands
Use Power Very Efficiently Only one of the two devices needs to be powered
Trusted Addition to other Technology Especially for pairing devices
Low Cost
Great! How do I know I
need NFC?

NDEF (NFC Data Exchange Format) While the modes of operation define HOW two NFC devices may communicate, NDEF defines WHAT those devices communicate. The list of NDEF messages is growing, and is designed to make complex tasks easier, as well as providing relevant and timely information and social connections. NDEF examples include links to internet content such as product web pages, videos & social networks, contact cards, ‘automatic’ Bluetooth or Wi-Fi pairing, GEO location information and many more. Furthermore, an NFC compliant device knows how to find and process that information automatically… just tap and go.

SOME DETAILS ON USE CASES…
IDENTIFICATION & AUTHENTICATION of consumables and accesso-ries to combat counterfeits or configure the main unit based on accessory
PARAMETRIZATION & DIAGNOSIS using a phone as extended user interface for small, sealed and unpowered devices
Use your phone or smart cards for ACCESS CONTROL to open doors or give access to machine configurations
• Do smartphones typically connect to your product via Bluetooth or Wi-Fi?

- Solution to consider: Connected tag IC + NFC Controller with integrated firmware IC
• Are you designing an access control solution?

If you answered yes to any of the discovery questions above,
then your application has the potential for NFC
Apple Pay uses NFC Card Emulation Mode to make the phone look like a credit card to the POS readers. With the release of iOS11, Apple will allow reading of READ NDEF messages from preprogrammed tags in iPhone 7 and newer. See the NDEFs section for more information on powerful use cases this will enable!
Key things to note: Apple does not write to tags. Unlike Android, Apple OS does not automatically process NDEFs; it requires the use of 3rd party apps.
