NFC is a wireless communication technology that allows two devices to talk by tapping them together.
NFC is not something new. It is based on RFID standards. It has been around you for quite some time. Think about the card that you use to pay for your highway toll and commuter trains, or the card that you use unlock your hotel door. It is just that recently, more manufacturers are adding NFC capability to their products making it more accessible to consumers. NFC operates at 13.56 MHz and transferring data up to 424Kbits/second
NFC is meant to be simple, quick and intuitive. No pairings and no elaborate setups required. NFC interaction requires nothing more than a simple tap. Due to the short communication range, it is not easy to have unwanted reading or tracking making it one of the appealing factor of NFC.
With NFC, you can tap your mobile devices to your everyday objects and certain pre-defined actions will be performed like exchanging digital contents, interacting with your social networks, changing your device settings or even open an application on your device. With its simplicity, NFC is touted to be the technology that bind the physical and the digital world.
As of today, more and more NFC-enabled devices are being rolled-out by manufacturers which include mobile phones, tablets, gaming consoles and laptops.
In NFC reader-writer mode, two components are required; a reader and a tag. Tap the two of them together and magic happens!
NFC tag is a small device with a microchip attached to an antenna. A small amount of information can be stored in the microchip to be transferred to another device. NFC tags are tiny enough to be embedded in all sorts of products such as stickers, key chains, labels and business cards
The good thing about NFC tag is that it is passive. That means, no battery or power source is required. NFC tags draw power from the device that reads them through magnetic induction. When an NFC device (e.g. your mobile phone) is near enough, it energizes the NFC tag and communication will take place.
An NFC chip or IC is the brain of an NFC tag. There are various type of NFC chips in the market. They differ mainly on memory size, memory layout configuration, security features, price and other extra features. We list in the table below, the types of NFC chip that we stock in order to help you to choose the one that suits your needs.
