Contactless reader isn't working

The title of this thread was updated from its original title: “Contactless reader”

Hey! Our contactless reader stopped working today. It shows as paired and ready but when we hit charge the green light doesn’t come on and we are unable to complete the transaction/tap the card. We have tried everything suggedted on the troubleshooting list like rebooting the iPad, and deleting and reinstalling the app and still the same problem. Any help would be appreciated, it is after hours for phone support.

I'm sorry to hear about your reader @Trickyincmtl. If you've been through all of the troubleshooting steps in our Support Center I also recommend doing a hard reset. To do this, press the Power Button on the reader for 20 seconds.

But if the reader still isn't working go ahead and call our Support team. Phone support is available 6am-6pm PT,Monday-Friday.

Mine also stopped working. It had paired fine over the last couple of months. I’ve tried all the troubleshooting steps mentioned in other posts. The device does show in my Bluetooth devices but not in square app.

Sorry to hear that @Jeeves

Did you try reinstalling the Point of Sale app?

Contactless reader stopped working after Android 10 update on my Galaxy Note 9. Just a red error bar on top saying "connect to internet." But I'm fully wifi-connected. Any suggestions?

Hey @gorovers,
