I got satisfaction using this to run my pos business. A customer who came for payment of school on seeing my traditional pos machine, was very discouraged and attempted going back. I beckon her to return as I have an application in my phone to generate the printout for her from. Upon successful transaction and printing of the receipt with this application, she expressed a total satisfaction and prayed God to bless me and my business. I affirmed a very big Amen. That was the beauty of super app.
