You will be required to enter your SSN in during signup. This is because Metal Pay is FDIC insured, unlike Venmo and Cash to my knowledge. Sign up process is easy and straightforward. App and UI is very beautiful.
I checked off 1 month usage as I was an Alpha Tester and seen what this app is capable of during alpha testing. Pennsylvania is not on the list of 34 states so I cannot verify the final product, but the Alpha was something to envy. Metal Pay Rocks!
I love Partiko, and one of the biggest reasons is that the developers respond almost immediately to feature requests. I've had two included in updates already, and more that they've said they would include soon. The branding and community around Partiko are amazing, and they really help boost Steem in general. The only minus is the lack of wallet features, but that's on their roadmap, and it makes sense to get all other features functional before adding the wallet in.
