Remember back last year when US Bank started allowing check scans on the iPhone?? Well, now the popularity is growing and this feature is now integrated into the newest version (2.7) of the PayPal app on the iPhone. The new feature does require that you keep the check for up to 15 days, but usually takes about 6 days for the transaction to happen. A great idea that I read from the source where I read about this was to add your regular bank account to your Paypal account and use this feature as a go between and you never have to go to your bank to deposit a check! Sweet!
