I'm glad someone made tech that can scan my card with the numbers on the back, thanks! Hopefully all the vendors I use start using your product. I'll also be looking into it for my own product!

Regarding your fraud models, I actually used to work in this area (I'm pretty sure we know a lot of the same folks at Uber!) and I'm curious where you're getting your fraud model data from? Do you have partners you're working with? Until you have enough transaction volume, how will you train your models?
