MHz is an easy to use application to read and write NFC Tags. No NFC Knowledge required. No programming required. 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 Waypoint of the current location.
