$5 ea, buy 4 get one free ($20 for 5).
I use Square, it's 2.75%. I did sign up for EMS, they are 2.25% I think.
Let me know. I looked into a few scanners, but they were $$. I even considered setting up an ATM.
I was thinking of a Kindle Fire ($60) and just having Square open, but there's no way to block out Square so someone couldn't get into the settings.
The setup you are talking about for $25, can it talk to Square?
I do have it so people can pay through my website, but it's yet to be used. I think it's too much of a PITA vs a swiper/scanner... pick QTY, swipe, done.
