Any suggestions? I hear there are phones out there that you can use as a replacement for a debit card machine, that'd be handy if I was out on a call and the customer was short on cash. Doesn't have to be too flashy as long as it gets the job done.
Fantastic thanks, now I just need to find a good phone to hook it up to!
I've found out with my years of having a cellphone, the most stable ones happen to be iPhones (sadly). I haven't had any luck with Android because they just keep breaking. I do like the OS though. I haven't tried the Galaxy S4/5 though. My sister has the S4 and she really likes it. But, in the end it's all up to you.
