Where can I use successful verification passed through your app/platform further? Can i got to bank for a loan and use it there?
Yes. Exchanges, cryptoexchanges, brokerage offices, banks, funds, online loans, etc. The next level will include, for example, services such as online orders of prescription medicines, or proof of a user's age for, say, the purchase of alcohol or tobacco. In a word, any services that require identity verification.
