Surely on more than one occasion you have found an NFC card by house when they were fashionable and right now you do not know or what it can do for you. In this small tutorial we will show you how to read NFC card information with an Android mobile .
I know it may be obvious, but for everything discussed here to work, your smartphone must have NFC connectivity or else you can not do anything . In addition there are several types of NFC cards, some may be compatible and others not, in this tutorial we will cover the RFID and compatible cards.
Several years ago, some companies like Sony took advantage of the pull of the NFC as a hook to attract potential buyers. Many of their devices included NFC cards which they called NFC Tags (NFC tags) and their function was basically to establish different configurations in the mobile. For example, when we arrived at our house we read the NFC card in question and configured the WiFi of our home. This does not make sense nowadays, because there are simpler methods that do not require NFC.
We will use the NFC Tools application that allows us to read and even write on NFC cards with RFID chips and compatible. Once the application is installed, we will only have to bring our device to the card and its contents will be read automatically.
With NFC Tools we can add actions to an NFC card. A very common example is to set up a card of this type so that when you bring your mobile phone closer to bed, turn off the Wi-Fi connection, mute the phone and activate the alarm to wake up the next day. The possibilities are endless.
NFC Tools is available in Play Store for free, although it has a Pro version of payment. It is a very complete application with a very intuitive interface that will give us all the possible information of the NFC cards.
