Conclusion
When equipped with the NFC standard resulting in a combination of RFID and smart card technologies with a close proximity requirement, smartphones are powerful interaction initiators between material objects, becoming communication and digital services. The three NFC modes cover a great variety of use cases with unlimited applications and unlimited imagination.
With a quick and simple targeted proximity gesture (the 3 “S” and “Tap’n Play”, see Introduction), the user can access geolocated, customized, contextualized and multimedia information finding applications in tourism, leisure, culture, technology, education, commerce, etc. These examples are not limited, because the NFC event is characterized by a spatial temporality (“here and now”) and identified components (like a tag identified by its UID or its content, or the mobile device’s holder identified by its IMEI) with the NFC reader/writer mode.
In P2P mode, NFC reaches a new dimension and allows to pair two devices that will then be able to exchange data (e.g. Wi-Fi, Bluetooth® and Li-Fi) when the initiator decides to do so (his/her will is induced in the fact that he/she brings the two devices into close proximity, with or without set-up during the first contact).
In card emulation mode, NFC not only allows to secure transactions with the implementation of protocols and cryptographic techniques inherited from smart cards technologies, but it also brings a major added value to static services hosted in smart cards ...
