Similar possibilities w/ 2D Barcodes?

– – – – –

Works by touching, instant Design can be merged with product Larger data storage possible Multiple use cases (app launch, BT pairing) Re-writable (if desired)

– Requires NFC HW – New to consumers

39

– No NFC HW required – Easily recognizable

Inconvenient (camera, focus, take picture) Large visual impact on product Very limited data storage Limited use cases (no app launch, BT pairing) Read-only


While Waiting: Unlock Game Content Angry Birds Magic • First 5 levels available Unlock more levels • Touch the phone of your friend!

Peer-to-peer • Touch two phones to ... • ... establish instant peer-to-peer connection – Uses LLCP (Logical Link Control Protocol) – Direct communication via sockets

• Content transfer – Slow connection (< 424 kBit/s, Bluetooth: < 3 MBit /s)) – Only while touching → great to exchange business card or unlock game items → transfer more data (e.g., images)? Use NFC to exchange Bluetooth / Wifi handover information 42


NFC Development Alternatives

Java ME Works on Series 40 and Symbian devices.

Limited use of smartphone features.

Qt Mobility Cross-platform API. Best flexibility and ease of app development.

Symbian Native Low level control over devices’ NFC support.

More complex, platform knowledge required.
