How it works
To get started, you just need a smartphone (or iPad), either an iOS or Android device. After downloading the Flint app, go through the sign-up process, during which you will be asked for personal information.
After activation, you need to complete your user profile by providing your bank account information, among other things. Then you are ready to accept payments.
To start a payment, enter the amount in the Flint app, scan the card using the phone’s own camera (or key in the numbers manually), then enter the CVV code and expiration date. Finally, ask the client to sign using your phone’s screen, and you are done.
