just came across this Fim50 series
up to 10,000 templates -
GT-521F52 is a beast on a fingerprin (;
Shared database you say? -
I have played with the identify/verify, makes sense what you guys said. My concern now is, it limits me to doing identification and verification within the GT-511C3, which was how it was designed.
Filling the sensor DB with stored template might be cumbersome (it is likely I would have templates that run into hundreds).
My thought now is to know the algorithm that was used by the device to do verifiy/identify so it can also be done outside the device (say, in a remote server).
Or come up with another algorithm that might do that.
In both cases, is it feasible? and is it something we - all of us (: could attempt? -
hi guys, so I was looking at the template data and am deducing (maybe wrong) that each fingerprint pattern (lets say index finger) will return different template data independent of how many times it was enrolled (3 times enrollment).
So I would like to know how the scanner identifies and verifies a user print.
i.e during identification, is the single print template (the template generated when you attempt to identify) run against the merged template of the 3 enrollment process?P.S what I want to try and do is run identification and verification not on the inbuilt template database but on a template itself.

Thanks @PaddeK for all your assist...finally its working all thanks to your efforts, one which involved to change minification in WebIDE settings from Esprima to Closure (online) - Simple Minification.
@allObjects my appreciation goes to you too.

Hi @PaddeK, were you able to write some complete examples?

getEnrollCount works as expected but checkEnrolled returns a 4111 error. looking at the datasheet thats 0x100F which is a NACK_DEV_ERR (device error especially if crypto chip is trouble) I hope this doesn't mean my GT511 has spoilt.

Hello @PaddeK, thanks for taking your time to try and sort somethings out.
I'm still getting a timeout error:timeout exceededI have tried several alternatives in calling the getTemplate function, yet it still times out.
Also calling the enroll(t) function results in this error:
Error { "msg": "Expecting a function to call, got Object", "type": "Error", "stack": " at line 1 col 1\nfn().then(res.concat.bind(res))\n^\nin function called from system\n" }after setting enroll with enroll = (t) => () => g.enroll(t); and passed it into the GT511.sequence array I got this error
enroll error: Error { "msg": "Function \"switchLED\" not found!", "type": "Error", "stack": " at line 1 col 6\nthis.switchLED(!!b)\n ^\nin function \"fn\" called from line 1 col 4\nfn().then(res.concat.bind(res))\n ^\nin function called from system\n" }
Just learnt that the GT511C3 uses the SmackFinger 3.0 Algorithm for identification.
Does that help in replicating the algorithm for identification/verification?
@PaddeK any other info on the GT-521F52 shared database on a network?
