I am the Finance and Operations Director for a domestic violence agency in Illinois. I am in the process of writing a fraud awareness policy and our agency insurance broker brought up an issue of cyber security that I should include in our new policy. In regards to this, it got me thinking that I'm not so clear on whether or not we are being safe when taking credit/debit card donations at outdoor events. We use Square and a tablet to take the donation information. The WiFi we usually use is supplied by the venue that the event is held at. Does anyone know if there are specific protocols they can suggest when taking outside donations? Thanks for any info.
I would contact Square and ask them about their hardware and software to answer that question. I would assume that the data will be encrypted when transmitted to square, but I don't know.
If the data will also be stored on the tablet, will it also be encrypted or somehow protected should the tablet be accessed or stolen? Any provider that people use should be able to answer these questions.

We used Square on a tablet for a local non-profit I worked with. In addition to what Christian suggested, I'd suggest investing in a VPN solution for your connection since you are using public wifi's. The connection with Square should be secure by default (but check with them) but if you do anything else on that tablet, it could be open to sniffing. Just adds a layer of security. You can find inexpensive options out there. I can't remember what VPN provider we used, but we paid less than $20 for a certain number of GBs of data that we calculated would take us over a year to use up.
Another option is to look into something like Mobile Beacon (http://www.techsoup.org/mobile-beacon) so you don't have to use the provided wi-fi.
Having said all that, I suspect you are probably ok using Square since they are going to be very worried about the network connection. The options I outlined just make things that much safer.
I hope that help. Oh, and welcome to the TechSoup forums!
