*If the current Firmware is lower than 1.19 you'll need to put the reader into programming mode. You can do this by pressing and holding the button on the front of the reader for about 4-5 seconds, two separate times. First time you press and hold you will see a blue light, second time the VP1 will turn and stay yellow. Yellow indicates programming mode, now you can use the app to update.
