NFC (3a Question)

In the class, we discussed about RFID. there is something very similar to it which I suspect most of uses. It’s called Near Field Communication (NFC). It is basically a wireless communication technology through which devices which has NFC can exchange data by simply touching them or bringing them close enough; typically within few centimetres. Overwhelming majority of smartphones, smartwatches has this technology. One of the most common use of NFC is to make payments through your phone/smartwatch. I personally usually use my iPhone to purchase something from the vending machine that’s located on 6th Floor in the Alter Hall so I’ll tell you the way I have to use it. 1. Double click my button that I use to (un)lock my phone. 2. Select the card I want to use. 3. For Authentication it uses face id. 4. After it verify my face I simply bring my phone near the black kind of thing where you insert your card or cash. 5. On the screen it shows like a message that’s the transaction is approve and near instantly I receive a notification on my phone of the transaction. Another common use of it is to transfer data between compatible devices. I know if you have an eligible samsung phones you can use NFC technology to transfer anything from your photos to your files. This is just one of the technology that’s fairly similar to RFID. Do you know any other kind of technology that’s similar to NFC or RFID?
