Amazon is reportedly about to launch its own mobile point-of-sale device, similar to Square and PayPal, according to a report from 9to5 Mac.

The publication got its hands on an internal Staples document that showed an "Amazon Card Reader" that would retail for $9.99. An exact date for the device's release was not made clear, according to the report. 

Amazon had been rumored to release a mobile POS device for some time. The company has never really denied its interest in creating one, as well as a smartphone. Amazon's new mobile wallet, which the company recently released without any warning, now makes more sense in conjunction with this report.
