Is Peer to Peer the real future for NFC?

Current status

• Despite being around for several years NFC is still in it’s infancy

• There are a significant number of applications using Reader mode, a relatively small number using card emulation mode but very few using Peer to peer

• Looking at payment/transit applications most use card emulation

• Even in a wallet


Moving forward

• As NFC evolves and matures more and more applications will be created

• what happens when I have lots of emulated cards?

e.g.

– Several payment cards

– A transit card

– A gym membership card

– An access card for the office


Lots of cards in my wallet

• As a user I would like them all to be ready to use anytime

• To be ‘visible’ at the same time they probably all need to share a common UID/PUPI

• To select one card out of many you use an Application Identifier (AID) – not all applications use AIDs

• Automatic selection means selecting them one at a time to see if the card exists in the wallet – slow!!!

• And.....all of the companies providing them really need to work together


So what happens today?

• Realistically we expect the user to select the right application before using it

• Some would argue that this is what users do now, they choose one plastic card out of their wallet and hand it to the cashier

• Surely, with a new technology don’t we want to make things better?..............


Is there a better way?

• We need a system where all the applications are available all the time

• Where the user can set preferences and priorities


Peer to peer

• Peer to peer mode is designed to support many applications from many providers

• Systems such as LLCP have a service discovery mode which means, for example, the POS terminal or subway turnstile can select the right application quickly

• Allows the user to present all their available ‘cards’ at the same time

• Much faster and easier to use


Benefits

• In scenarios where only one ‘card’ will work it is selected automatically

• In scenarios where one of several ‘cards’ will work the user can still choose

• The user can choose preferences/priorities and disable some applications

• Avoids delays caused by having the wrong application enabled


So.............The question

Is Peer to Peer the real future for NFC?
