When you swipe your credit card at a local business, Amazon wants its cut.
And its new product aims directly at Square, the company started by Twitter co-founder Jack Dorsey.
Amazon (AMZN) Local Register will charge much less than Square: Just 1.75% of the value of each swipe for businesses that sign up by October. It will be 2.5% after that.
Square charges 2.75%.
Amazon also is basically giving away the hardware used by small businesses, saying that customers' first $10 in transaction fees will be credited back to them to cover cost of its new card reader.
