![]() ![]() Once we had done this we could then hold our phone close to the tag and our phone would automatically scan the tag and open the message in a window on our phone. Our NFC tools app allowed us to directly type text into it and then write this text directly onto the NFC tag. ![]() A simple way to think of a kilobyte is it can contain a 1000 letters, or characters, including spaces! As an example this last paragraph you read is 653 characters long.ġ000 letters isn’t massive but it is enough for a short message, say up to roughly 150 words. Whilst actual amounts vary across different tags, our tags could hold 1 kilobyte of data. Apart from the cool power stuff NFC can contain a small amount of data. On the NFC chip there is a super fine coil of wire which acts as an inductor and, put simply, can induct power from the transmitting device. NFC tags are brilliant in that they don’t need any power supply to operate and they rely on the powered “active” device, in this case our phone. To read and write to the NFC tags we used a free android application on our phone called “NFC tools”. We bought some small stickers and began to play with them. They can also increasingly be found embedded into objects like rings and necklaces. ![]() We used some “Mifare” tags for our experiments and these are available in all kinds of shapes and sizes from small stickers to blank credit cards, keyrings and more can all be found online. NFC tags are available in all kinds of formats and types. If you have an NFC enabled phone (Android or Apple) you can use your phone to both set up or “write to” an NFC tag and to “read” the contents of an NFC tag. Very useful but it’s true to say that there are more fun things we can do with NFC!įirst thing we need to check is that we have an NFC enabled phone you can usually turn on or off the NFC function on a mobile phone in the settings. NFC or Near Field Communication is the technology that contactless payments with phones use where a phone can be placed near a terminal and a payment is made or when “smart cards” are used in a hotel or an office to undo locks on doors to give people access. With the summer coming to an end, why not cap it off with a NFC enabled adventure? ![]()
