I have a scenario where I want the user to scan their thumb impression upon arrival. Their information should appear in front of us, and their thumb impression should be saved in the system.  
When they scan their thumb for the first time, we will register them and then add the services they want.

Can we implement an idea like this???  
If Yes, plz suggest any idea…

What you describe requires hardware interaction, so I do not think you can do it directly with Tryton. But you probably need to develop a dedicated application for the chosen hardware and integrate with the Tryton API: [User Application — Tryton server](https://docs.tryton.org/latest/server/topics/user_application.html)

Are there any specific biometric scanners that have been used successfully with Tryton in the past? or would we need to store the data externally and verify it through an API?  
What would be the best approach to trigger user registration upon their first thumb impression scan?  
Please suggest.
