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: Í » Pay Parking fee Í » Purchasing fuels Í » Links to an up-to-date weather report website Í » Location-relevant map Í » Special discounted travel offers Í » Next bus/train arrival time Í » Taxi services Í » Emergency calls Ease of use: This criterion refers to Ížthe degree to which a person believes that using a particular system would be free of effortÍŸ ‡ 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.  Ã‚‡ Security: Implicit security features (e.g. embedded encryption) and ease of securing the technology.  Ã‚‡ 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.
