Take credit card payments with your iPhone 3G and 3GS only for now

Intuit, the maker of the popular QuickBooks and TurboTax software, has approached the accessory maker Mophie, and they have both come up with a card reader and application for the iPhone that allows small businesses to accept credit card payments on the go with their iPhone.

GoPayment has been on the market for more than a year and has already processed $35 million in transactions for small businesses. In addition to faster merchant account activation and integration with QuickBooks Mac, this latest version offers easier navigation with the ability for customers to sign their bill via the iPhone touch screen.

Its also possible to now add inventory items to receipts, which can instantly be e-mailed or sent by text to a customer for their records. To make GoPayment affordable for the smallest of small businesses, it also offers new simplified pricing with competitive discount rates and transaction fees.
