Estimado cliente,

Ese es un ejemplo de como usar nuestra librería en una aplicación web (lenguaje PHP). Con respecto a su duda, si es posible usar dichos gestores de base de datos.

Si tuvieras más dudas me avisas.

Cuando mi aplicacion esta en marcha, obtengo este error:

GrFingerX.Initialize is not a function.

Adjunto el GrFingerService.php

Estimado cliente,

Verifique el archivo GrFinger que se encuentra en la carpeta client-side:

//Must change to the path that contains the files "enroll.php", "identify.php" and "verify.php"

var url_server="http://192.168.0.100/GrFingerService/"

Hey team.

i have all these installed.

1. The Fingerprint SDK 2009 must be installed.
2. An Apache server must be running.
3. IE installed and configured to allow ActiveX.

i have configured the path to point to php scripts.

i place my finger on the finger scan i can see the image of my finger on the enroll screen, but this template is not saved in  an emulated database ie txt file.

what might have caused all this

if i can get this sample template saved then i can be able to upload the image as a blob

Dear customer,

You probably are not saving correctly the template or extracting it.

Try to check if the server is receiving the template.

Because, if you can see the image, you just need to extract it, send it to the server and store.

sir when i go to the inside of my server folder i cannot see it.but when i place my finger i can see the image and i can see being told "sufficient enrollment".

Hey everyone i have been working on this finger scan fr 10 days. i have only changed the path to point the PHP scripts , no more changes i have made in the code.
