Nfc Based Security System

Nfc is a technology that has been around already for years but has gained much attention after apple announced that the new iphone 6 line was fitted with the technology for credit card less payments.

Nfc based security system.

But nfc s short range in a sense serves as a safeguard against hackers. Nfc software in physical security nfc is a type of electronic correspondence that is based on the induction of electromagnetic fields developed between two antennas that use nfc technology. It evolved from radio frequency. Securing data exchanged through rf channel through cryptographic methods.

The communication between two devices takes place through a stack of communication protocols. Nfc stands for near field communication and it allows phones tablets laptops and other devices to easily share data with other nfc equipped devices. This can be used to communicate with active tags to the information exchange with a user. Nfc systems are interoperable and open by default.

Nfc is just a platform for establishing communication between two devices. Today most of the mobile phones have nfc interface. First he d have to be close enough. Using cryptography implies the usage of cryptographic keys on both sides of the communication.

Access solutions for bluetooth and nfc enabled device s mobile access is the use of a bluetooth or nfc enabled mobile device such as a smartphone tablet or wearable for controlled access to doors gates networks services and more. Nfc near field communication is a wireless technology based on rfid radio frequency identification at 13 56 mhz that establishes a communication between the devices by bringing them in close proximity. Like other proximity card technologies nfc is based on inductive coupling between two so called antennas present on nfc enabled devices for example a smartphone and a printer communicating in one or both directions using a frequency of 13 56 mhz in the globally available unlicensed radio frequency ism band using the iso iec 18000 3 air interface standard at data rates ranging from 106 to 424 kbit s. Near field communication nfc is shaping the future of mobility and is becoming the system of choice for mobile payments.

This marks the one major difference. Data is now protected through cryptographic means nfc system is not open interoperable anymore. In any case the emv convention which is at present used to give the expected security to nfc based installment frameworks has two genuine vulnerabilities between client installment gadgets and the dealers purpose of offers which could prompt clear dangers for clients.
