Hey! Thanks for reaching out and, yes, depending on the reader, you will either need to plug it in or pair it to your phone.

To update the firmware on your Square Reader for Contactless and Chip:

Open the Square app on your device.
Pair the reader to your device. If this is a reader you plug in, just simply plug it in.
The firmware update will begin automatically. Keep in mind, you won’t be able to take payments while the reader is updating.

This process usually takes 5-10 minutes. Once finished, you can continue accepting payments as usual.

Let me know if this helps! Thank you!

How can I tell if the firmware was updated. When I paired both readers, I have a wireless reader also, I saw no indicator regarding an update

my app only showed I could process payments

If you can process payments, then your devices should all be up to date and you are good to go. 🙂

You can manually reset your reader by following these steps:

Hold the button on the bottom of the reader for 15 seconds.
When you see 4 red lights, release the button. Keep in mind the lights will flash orange first- keep holding until they're red.
Tap on the button one time to get green lights.

Once you've reset the reader, pair it to your phone again. Any outstanding updates will be pushed through then. Please let us know how you go!
