Pipeline Data has announced that its Aircharge system is now compatible with a range of BlackBerry devices. The AirPro service lets you make over the air credit card transactions using a BlackBerry 8300, 8800, 8700, 8100, 7780, 7290, 7280, 7130 or a 7100. Right now, it’s only available on Dobson Cellular, but since AT&T’s going to be picking it up, anyone else under the AT&T umbrella shouldn’t have any issues signing up once the deal goes through. I guess until near-field wireless transactions get ironed out, we’ll have to do it the old-fashioned way. That is, if you can call taking someone’s piece of plastic, translating its magnetic strip into a signal which is emitted into the sky, received by giant towers, and transmitted to a multinational corporation which temporarily supplies funds for goods and services old-fashioned.
