Square Cash let you send money over email, iPhone or Android. There is no signup required for transferring money within the US and it's free. You can use a debit or credit card as the source and destination.
Square’s advanced auditing systems use live monitoring programs to analyze transactions in real-time. This keeps Square Cash senders and recipients safe. When we notice suspicious activity, we alert you and prevent further payments from being sent. Square Cash uses the same fraud detection infrastructure that monitors millions of daily Square Register transactions.Try it !
