Thanks for the input kkgator- we are going to go with square. Looks like it will do all we need for a while. We have an iPad,without cellular, we are going to start with and see how it goes using hotspot. If it gives us trouble, I guess we'll have to suck it up and buy a new one.
From what I was reading, it seems like it will store card info, even if no current connection. Then I guess do all of transmitting, when it comes back up... am I reading it wrong?? I guess there is the risk of having a bad card... but better to take that chance, rather than have a line of people wanting to by your food, and having to turn them away. Ive always been a gambling man...
Thanks again to all who have pitched in!!
