Good afternoon.
Contacts of potential clients-doctors are collected at the exhibition, they are invited to enter their contact details on the computer on the first day of the exhibition and on the second day receive business cards at the same stand. What is the best way to organize independent data entry? There was an idea with forms in excel, but a doctor - an inexperienced user can screw something up. Ideally - full screen fields for entering full name, address, phone number, etc. just with the add button, which would enter all the data somewhere in the database and clear the fields. There is Internet access.

Answer 1

Google Forms, right?

Answer 2

On the day of the exhibition, some local bearded administrator will write a phish form with 3 huge text boxes for a beer on his knee.
Well, or ask a friend, an acquaintance, it's an elementary thing.
