What is Near Field Communication?
A technology related to RFID that allows wireless data transfer between devices, or between a device and a tag.
Embedded in Tags Laptops Phones
Embedded MicroSD add-on
Applications
Information links (like QR codes), Social media check-ins, Smart posters
Peer-to-peer transfers – photos, contact info, files
Applications Access – doors, computers, car ignitions,
Public transportation, event ticketing Quick set-up of other services – Wi-Fi or
Bluetooth pairing Mobile payments
Missouri State has selected an NFC system to replace magnetic strip cards for campus IDs
Technical parameters
13.56 MHz Low power. Operates at close proximity only
– up to 10 cm, but in practice averages 4 cm max
Can be read-only or read-write. One-way or two-way communication. Only one side of the connection needs to be
powered. Other side uses induction (like wireless charging)
Can store/exchange up to 1MB of data Tags currently run approximately $0.50 each
Why NFC in addition to RFID, Wi-Fi and Bluetooth?
Fast connection Simple to use Low power consumption
Shorter distance than RFID means more security Exchanges data in two directions (RFID is one
way) Compatible with some existing RFID tags
Faster set-up than Wi-Fi or Bluetooth Can be used to speed up their connection process
NFC vs. QR Codes
NFC Tags can hold up to 1MB of data
NFC can be passive or active – Allows two-way exchange of data
NFC tags can be embedded in anything (unobtrusive)
Active NFC currently limited to certain phones
QR codes hold 7,089 characters
QR codes are passive only – One-way data
QR codes are ugly/jarring
QR codes can currently be read by most phones, but user must open app and scan the code
Players in NFC
AGAINST Verifone (dominant maker
of point-of-sale hardware) Phones makers –
Samsung, Nokia, Blackberry, HTC
Google Wallet and Nexus ISIS – AT&T, Verizon, and
T-Mobile Visa/Mastercard Bank of America/Citibank Gaming – Angry Birds and Fruit Ninja
Objecs – NFC gravestones
PayPal/eBay Square Retalix
UNDECIDED
Apple
FOR
NFC in Libraries
Library card replacement Payments Reservations One touch setup of Wi-Fi access Self checkout - http://youtu.be/2C_bvyqJVfU
Near term - Powered NFC checkout device – tap card, tap book, walk out
As more patrons have NFC phones – tap phone to book, walk out
NFC in Libraries
Information tags on books/media Bibliographic info Reviews Author info “You might also like”
Information tags on displays/signs “More info on this subject” tag Related books/materials in this library Instant e-book download from
poster/display
Concerns
Security and Privacy Concern about spoofing tags, snooping on
data exchange, activating tags at greater distances Can be Pin number protected Can be encrypted Can be shut down remotely Critical data can be kept on separate secure chip
in phone
MasterCard has said it is as secure as any credit/debit card.
Concerns
Digital divide We could still issue the NFC-enabled library
cards to provide much of this functionality to users without mobile phones
Mobile phones are becoming ubiquitous 6 billion phones in the world Some countries over 100% mobile phone
