Adding "take a picture" or biometric to Knack input


Any idea if it is possible to activate a cell phone camera to take a pic as a Knack input? Currently I use the "signature" input field to obtain client signatures after a training session with one of my trainers. I would like to add either a biometric input (thumbprint) or a picture of the client after training instead. I have had a couple of my trainers "cheat" the system and sign for services not rendered.

It's both a security and HR issue.

Any ideas?


Are you thinking something like this?

I've used for years and it integrates well with Knack and Integromat. Here is the form widget you can integrate to take photo with a cellphone or webcam on a computer easily and upload it to knack.
