You would need to contact your carrier or a financial institution where you live to see if they offer the service(s) that you would need.

PayAnywhere Processing

There is other services available as well but given you never mentioned where you're from, makes it kind of hard to say whether or not they'll work. Some only work in Canada, some only work in the U.S. etc etc etc.

ROAMpay, they support Blackberry, you will have to check if your individual model Blackberry is supported. They have tons of merchant partners they work with also, some give you the ROAMpay reader free for hooking up with them. Wait'in for BBM Money to roll out.
