Amazon, a competitor to almost every merchant, has rolled out it's own small merchant mobile point of sale solution. It will be interesting to see how they get on against the folks they are undercutting.
Business that sign up for the point-of-sales system before October 31, 2014 will pay a promotional rate of 1.75% per card swipe on major credit and debit cards until January 1, 2016. Then the price will in increase to 2.5% per swipe. Merchants who sign up after October will also pay the 2.5% rate.
