Electronic signature capture

Hi,

Is anyone out there using Cache to capture electronic signatures? The device would have to be called from a telnet session.

Thanks in advance,

Hi Dmitry,

We were looking to connect a device (the one shown below) allow our staff to save customer signatures for goods and safe them in a png or jpeg file. Unfortunately, although the vendor provided us with an ActiveX file, cache couldn't use it. What we were looking to know if anyone has used a similar device which cache can talk to, and who supplies it.

Wow, thats actually very different from what I expected.

So, now it depends, what is your application right now. If your application is a WEB Based, or textual terminal application it will be very different.

If it is a WEB, so, I think you can try some TWAIN libraries, as this device should support twain.

Or, it looks like it can just export image files somewhere, where you can just catch them.

Can you give some more details about your application and expected workflow?

Hi Dmitry,

I am trying to get this work on a textual terminal (I have gotten it to work with a web page). I have already been in contact with Intersystems, and we have tried to get it to work using the ActiveX component supplied by the vendor. But it crashes the system, and the vendor says they don't support cache. So I was looking to see if anyone had got  a device similar to the one below to work with cache.

My understanding is that the Caché application is terminal based (accessed on the client PC through telnet).

The signature device connects to the client PC using USB.

So the question/challenge is for the terminal-based application to send a request to the signature device when a signature is needed and to receive the signature image.

Seems like you need a daemon running on the PC which uses the signature device's SDK to communicate with it. The daemon would then exchange messages with Caché to manage the signature process -- possibly via web services or web sockets.
