NFC – What is it ?
NFC is an extension of Radio frequency identification.
NFC or Near Field Communication is a short range high frequency wireless communication technology.
A radio communication is established by touching the two phones or keeping them in a proximity of a few centimeters.
HISTORY OF NFC TECHNOLOGY
In 2004, NFC Forum was formed by Nokia, Philips, Sony to set standards for NFC . Every NFC enabled device will have an “N-Mark” trademark ,developed by NFC Forum.
In 2006, first mobile phone( nokia 6131) with NFC was released by NOKIA.
In 2010, first android phone SAMSUNG NEXUS S with NFC support was released.
Sony introduced "Smart Tags", which use NFC technology to change modes and profiles on sony smartphones.
OPERATION OF NFC
Near field communication is based on inductive-coupling.
NFC works using magnetic induction between two loop antennas.
So, NFC use an initiator and a target; the initiator actively generates an RF field that can power a passive target.
Operating frequency is 13.56 MHz and data rate varies from106 Kbit/s to 424 Kbit/s.
ADVANTAGES OF NFC
Reduces cost of electronic issuance .
Secure communication.
No special software.
No manual configuration and settings.
No search and pair procedure.
NFC can be used together with existing technologies like Bluetooth and thus act for longer range also.
NFC uses are practically limitless.
DISADVANTAGES OF NFC
The system has the limitation that it can be operated only with devices under a short range i.e. around 10 cm.
The data transfer rate is very less at about 106kbps, 212 kbps and 424kbps.
Eavesdropping
Data Corruption and Manipulation
Theft
CONCLUSION
Mobile handsets are the primary target for NFC and soon NFC will be implemented in most handheld devices.
The advancements in mobile wireless technology and communication standards have enabled usage of contactless and NFC based payment models.
The mobile wallet based payment model is gaining considerable momentum and is currently being seen as one of the key payment model, to promote contactless payment processing practices.
The mobile wallet technology enables the end-users to make payments with their mobile wallet accounts, without having to use credit or debit cards and hence this technology can also help users that do not use credit or debit cards.
