Amazon takes on PayPal and Square with mobile payment accessory
If you're an iOS user, you're in the clear, because the Local Register works with the newest iPads and all iPhones going all the way back to the iPhone 4. However, the only Android devices that are compatible are the Samsung Galaxy S3, S4, and S5, as well as the Amazon Fire HD and HDX. Surprisingly, not even the new Amazon Fire Phone is listed in the compatibility. Even worse, the early reviews say that you cannot use your existing Amazon account, and are forced to sign up for a new account in order to use the Local Register.
If that still sounds like a good deal to you, it will cost $10 to get an Amazon Local Register card reader, but that cost will be credited back with the first $10 in processing fees. Amazon is obviously trying to offset those who would get a reader and never use it (for example, I have both a Square reader and a PayPal reader, and have never used either.)
