You must be aware of devices interacting with each other without any actual contact between them, most common technology used for this purpose is Bluetooth and Wi-Fi and these are the technologies which are known to almost every second person.
But as we know the world is ever expanding and with this ever expanding world there comes a new technology NFC which helps in data exchange between two devices without any physical contact.
Near Field Communication (NFC) is based on Radio Frequency Identification (RFID), NFC is a set of standards for smartphones and other similar devices through which devices establish a connection between by taping each other or by coming into close proximity which is not more than 4 cms.
Communication is possible between two NFC devices or between NFC device and other devices containing NFC tag. NFC tag is an unpowered chip that enables the device to communicate with other NFC device or the device with NFC tag i.e. communication is also possible between the devices having NFC tag.
How Near Field Communication (NFC) works?
One of the very obvious question that strikes into mind is how does NFC works like Bluetooth or Wi-Fi?
Bluetooth and Wi-Fi and NFC all three are wireless mode of communications but Bluetooth and Wi-Fi uses radio transmissions and NFC focuses on using electromagnetic radio fields.
It works using magnetic induction, when the communicating devices comes in contact a magnetic field is created that bridges the space between the devices and as a result they can provide information or provide and read both.
History of Near Field Communication (NFC)
NFC is based on RFID (Radio Frequency Identification) which was discovered in 1983, but after many research; main existence of NFC came in 2004 when Nokia, Philips and Sony established the NFC forum. So 2004 is actually the base from when this technology came into existence. After many research work on this technology in 2006 its tags known as NFC tags came into existence and then the commencement was made of the use of this technology in smartphones and other devices.
Nokia 6131 released in the year 2006 was the first NFC enabled smartphone.
Samsung Nexus released in 2010 was the first android based NFC enabled smartphone.
NFC enables secured channel of transmission and also uses encryption methods while sending sensitive data such as credit card numbers and other sensitive data.
Apart from these advantages there are few disadvantages attached with this technology that is eavesdropping, relay attack, data modification, lost property are possible in this technology, so measures are yet to be taken to make it more secure.
