Card readers not working on handhelds

[Butcherandbar]

About 3 times a week the card readers stop working on our handhelds. I have to go in to the card reader test app to get them to work again. It's ridiculous. Can anyone explain why they keep shutting of and how I can prevent it from happening?

There was an issue with the latest firmware update and card readers, not sure if this is what is affecting yours but might be worth trying https://central.toasttab.com/s/article/Toast-Go-2-Card-Reader-Payment-Blocking-Issue
