A free app for Android, by Peter Munch-Ellingsen.
MIFARE Ultralight is a tool that allows developers to test and verify the functionality of a MIFARE tag, a type of tag used in the bootloader of a wide range of NXP Semiconductors mobile devices. This app allows developers to scan a MIFARE tag to see what its default value is and if it can be unlocked and read. If it is not set to a default value it will not be used for anything. This allows developers to create and test a MIFARE tag without having to connect a device to the computer to see if it works. This app is compatible with both Android and iOS devices.
