MHz is an easy to use application to read and write NFC Tags.
It comes with different write features, such as WIFI switch, which once written on the NFC tag, will work as an ON/OFF switch. Enabling WIFI if it is disabled, or disabling it, if it is enabled.
To read the NFC Tag and perform the task written on the Tag, place the back of the device close to the NFC Tag. The Tag will be read and the task performed.
Do not launch the application, to read the NFC Tag and perform the task. Just bring the device close to the Tag, and the Tag will be read.
If you have the Maps Application use the Maps Bookmark write facility to write a NFC Tag that will automatically create a Maps Bookmark of the current location.
Great for locating where you parked the car. Just stick the NFC tag on your car dashboard, and bring the Phone close to the NFC tag when you want to remember the location. No need to launch the Maps application, just bring the phone within touching distance of the NFC tag and the Maps application will create the bookmark automatically.
