Chase customers have been depositing checks via iPhones for months now, but from today millions of PayPal users will never have to go to the bank again. Well, other than to steal pens or use their toilet.
To use the app, you must take a photo of the front and rear of a check, whizz them off digitally, and then wait about six days for the money to show up in your PayPal account. Pretty easy, and it's something I'd definitely be using if I had an iPhone. Or got paid in checks. [iTunes via 9to5Mac]
