We are a booster club with 2 concessions stands at the school and having a quick tap to pay option for all the students who don't carry cash is a necessity. Our parent volunteers are not always the most comfortable using their phones for tap to pay for security reasons. At times we can have over 100 transactions and that's a lot of tapping on your phone and possible date security issues. Being able to use the app on an iPad, a centralized device, for tap to pay, or an external swiper, is much more efficient. We love using Zeffy for everything else but may have to switch back to Square if we cannot figure out how to take in person concessions sales payments by the time school starts again.
