Amazon could be preparing to launch its own mobile credit card reading hardware in the coming weeks, according to internal Staples documents hinting at such a launch that we’ve obtained. According to the documents, Staples stores will prepare next month to stock a new product called the “Amazon Card Reader” alongside existing card readers from Square, PayPal, and Staples’ own in-house brand. The small hardware, which will likely connect to smartphones to process payments, will cost $9.99, according to the Staples internal sales systems. Interestingly enough, Amazon just launched a new Wallet app for smartphones last week, so the upcoming hardware will likely connect to that software. An exact launch date for the product is unconfirmed, but Staples has asked its stores to wait until Tuesday, August 12th to put up new signage related to the Amazon Card Reader.
