THE best way to send/receive money to/from friends, for free on iOS and Android, is Square Cash! No account is required to receive money – you can send using a cell phone number or email address and all the recipient has to do is enter their debit card number and click one button. The transaction will appear in your account right away – no waiting! Also Square Cash will give you and each person you invite $5 for free, which is automatically added to your bank account when you make your first transfer (account required). This service is MUCH easier than PayPal and FASTER! Check out the video below.
