If you haven't already @ppilor , you should look into the possible legal application and use cases for this.
With the increasing amount of contracts and legal documents now beign signed electronically, I think that a feature like this could be a great addition to DocuSign or AdobeSign and the like.
It could also be useful for all the apps and services where you need to provides KYCs and a picture of yourself at the registration, eg Winamax, CoinBase, etc.
I'd be interested to know if you'll go further than just the autograph collection ! let me know :)
@ryan_alx_ibh Thank you! I appreciate your comment.
Yes, I thought about that too when creating this idea. This could be very helpful for a lot of people and companies.
Additionaly my last innovation idea was NFT marketplace - You could sell video autographs in the app as NFT. When we add place and time on the video the value of the autograph could increase (for instane: autograph signed after winning championship battle by a star taking place in that battle). People could earn money using this app.
