NFC is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few inches. What are nfc tags used for? Another cool application of NFC is start up your pc using NFC by waving your smartphone on your laptop both under the same network. NFC loyalty cards can be used to track customer preference, offer him discounts. With handful of software, couple of NFC tags, automation hardware like WeMo you can hack your room lights to work on voice command. This is best used in Bill Gates’s techno-utopian Xanadu 2.0 mansion where NFC is placed in their id cards so, when the visitors enter the mansion temperature and lighting conditions get adjusted according to demographic of visitors. Use the comments section below and let us know how you use NFC in your daily life.
By using micro controller like an Arduino, you can control almost any electrically operate machines like toaster, heater even your coffee maker using NFC radio shield. It uses a low-power communications protocol between two devices, and it allows consumers to pay for things using their smartphone. NFC is a form of wireless communication using radio frequencies; it operates at a frequency of 13.56 MHz and transfers data at up to 424 Kbits/second.
Credit card security is always a concern for consumers, and through the years many systems have been implemented to protect buyers and their finances, from the use of pins to dual authentication when using credit cards online to embedded chips, a technology that is now being phased in also for consumers’ credit cards in the United States. NFC, with its high security standards as well as convenience, seems to be the answer to the credit card security concerns. As the acronym of NFC implies, Near Field Communication provides information exchange between systems in close proximity, usually no more than a few centimeters (typically 0-5 cm).
NFC can be considered an advanced version or extension of RFID; this wireless means of communication is widely used to track items thanks to smart bar codes; in fact, NFC was developed out of the HF RFID readers and tags. A device with an NFC smartcard chipset can very easily be configured to work as a credit or debit card.
Phones with embedded NFC use a wireless non-contact system based on RFID and can transfer data to and from another device remotely (but in close proximity) – for example, a retailer’s POS terminal. NFC technology can be used to verify memberships at gyms or clubs or even to replace keys. Some users believe NFC is similar to Bluetooth technology; in reality, NFC requires less power consumption (a must when using cell phones to maximize battery life) and allows pairing of two devices in a much simpler way.
