BBM subscribers will soon be able to send or receive money via PayPal, in the middle of a BBM chat
After setting up PayPal on BBM, sending money is as simple as clicking the PayPal icon, tapping out the amount of money you want to send, and clicking on another button. You don't even need to have the PayPal app installed on your BlackBerry, iOS or Android phone. And employing the feature makes a lot of sense if you're already in a conversation (via BBM) with someone whom you owe money to. Even better is when the person you're chatting with owes you money. You simply tell him/her to use PayPal to send you the money owed to you.
The PayPal feature is another way that BBM makes it easier to handle your finances. BBM Money already allows you to make instant mobile payments and send prepaid mobile credit.
