Hello Folks,
It has been a while!
Well, i came across this device (GT511C3) while doing some research on a project and realized it's cool but there isn't any publicly available info on how to get started or communicate with the device using PICAXE. I decided to spend a few hours which later took a day (for all the reasons that those who had used the device also encountered) to write a getting started basic BASIC code -- which simply for a start, indefinitely switches / toggles the fingerprint scanner (blue light) ON and OFF at 1s.
Please note, my attention in this regard is to make a very quick and simple testing code and disclose it to those PICAXE enthusiasts who are unaware of it.
I hope my piece will facilitate the getting starting process and hopefully there will be of course better improvements and cool projects that will emanate -- that i leave as homework to the PICAXE enthusiasts and those with spare time on their side, to exercise their PICAXE programming skills and feedback to the forum.
Those interested may find and peruse the attached files for details and let me know of any issues. To see the response from the FPS device, use a terminal program.
The information in the following links are handy and should be perused as well.

Take special note of the GT511C3 or variant pin-out connections, the TTL level (3.3V not 5V) and the serial command communication packet protocol structure.
GT511C3 FPS Generic PICAXE Chip Interfacing (UART/TTL levels only)
Pin 1 UART Tx (3.3V) <-------Black wire--------> Rx (UART/TLL 3v3 or 5V)
Pin 2 UART Rx (3.3V) <-------White wire-------> Tx (UART/TLL ~3v3) NB: if using a 5V Powered PICAXE, drop it TTL voltage (e.g. use a 1K/2k2 voltage divider)
Pin 3 Ground (0V) <-------White wire--------> Ground (0V)
Pin 4 Vcc (3.3 to 6V) <-------White wire-------> 3v3 or 5V (if you mistakenly swap the Vcc and Tx around, the FPS device is robust and won't pop instantly)
If purchasing the fingerprint scanner / reader device, remember to as well buy the interfacing cable (https://www.sparkfun.com/products/10359).
I really think the future goal(s) of the "senior members" should be to discover any cool / advance device out there and see how we can make our little contribution to Revolution Education, by doing a getting started piece for the PICAXE community, especially to the novice and to attract new comers / users.
All the best and have fun with it during the fiesta
