NFC technology Essay
The NFC Forum has identified three basic use cases for NFC: connection, access, and transactions. All three have application in transport. Public
transport requires infrastructure for NFC Ticketing + NFC Payment Transportation Uses:
ͻ Pay Parking fee
ͻ Purchasing fuels
ͻ Links to an up-to-date weather report website
ͻ Location-relevant map
ͻ Special discounted travel offers
ͻ Next bus/train arrival time
ͻ Taxi services
ͻ Emergency calls
Ease of use: This criterion refers to ͞the degree to which a person believes that using a particular system would be free of effort͟ Cost: It regroups direct costs (e.g. cost of the technology, cost of implementation) and indirect costs (e.g. infrastructure operation and maintenance).
Reliability: The purchase process should be flawless as it involves a financial transaction.
User/Market Acceptance: This criterion represent the degree to which the user and the different stakeholders are already consenting to accept a technology for payments. Security: Implicit security features (e.g. embedded encryption) and ease of securing the technology. Flexibility: Degree to which the technology can be adapted in many different applications.
Maturity: Development state of the technology.
Speed: Implicit speed of the technology for payments.
Scalability: Ability to grow. Usability in small and large environment.
Upcoming Bluetooth 4.0 low energy protocol will be consuming even lower power than NFC as of now.
NFC alone does not ensure secure communications is vulnerable to data modifications.
Advantages over Bluetooth
Almost instant connection (around 1/10 seconds) in comparison to pairing procedure of Bluetooth.
Low power consumption and could work (alternatively) even when one of the device is powerless .
NFC is compatible with existing passive RFID (13.56 MHz ISO/IEC 18000-3) infrastructures.
Shorter range makes it suitable for crowded area with high interferences.
