Perhaps the dead-easiest way to send money to someone else from your iPhone is by using Square Cash.
You might know Square from its popular card reader accessory for smartphones and tablets, but Square Cash is a bit different. It's an app that lets you easily send money to someone else, even if they don't have the Square Cash app themselves at first.
All you have to do is link up your Visa or MasterCard credit or debit card and then enter in an email or phone number of the recipient. Put in an amount and then the money will be on its way.
Essentially, it's a lot like PayPal, but it's a much simpler interface that's really easy to use. It has the essentials and nothing else.
