My Reader won’t accept Credit Cards
If you are having trouble accepting EMV or tap transactions, try the following steps:
- Ensure your reader is fully charged and that you have a strong Wi-Fi or cellular data connection.
- If the reader and device are more than ~3 metres apart, the reader will have trouble maintaining a consistent connection. Move your reader and device closer when in use.
- Verify your reader is connected:
- Tap the three horizontal lines in your Square App.
- Tap Settings > Card Readers.
- Confirm the four numbers in your settings match your reader’s serial number.
- Make sure you see a single green light on the reader before you ask your customer to hold their card or device over the reader to make the payment.
- Double check that the chip on your customer’s card is facing up.
- Keep your customer’s card in the reader until prompted on your device’s screen to remove the card.
My Reader won’t pair with my device
Before you attempt to connect your reader, make sure your reader is ready to be connected.
- Confirm Bluetooth is turned on in your device settings.
- Ensure your reader is fully charged.
- Check that your device is connected to the internet.
Once your reader is ready to be paired, you’ll want to open up the Square App.
Note: the reader pairs to your device through the Square app – not through your device’s Bluetooth settings. To do so:
- Go to the Square app and tap the three horizontal lines.
- Tap Settings & Card Readers.
- Tap Connect a Reader. If you are using an iOS device you will need to select Reader.
Verify your reader can go into pairing mode. To put the reader into pairing mode, press the reader’s power button for 3-10 seconds until you see 4 orange blinking lights. Immediately release your finger when you see these orange lights. If you see red lights, you’ve held the button too long and you can try again.

My Reader won’t charge
Please try the tips below – they usually fix most charging issues customers encounter with the reader:
- Make sure the reader is firmly plugged into the USB hardware hub of your Square Stand or into a grounded outlet.
- Try plugging the power adaptor into a different outlet.
- Force shutdown your reader. To do so:
- Plug in the reader for at least 20 minutes to be sure it’s charged.
- While the reader is charging, use a small object like a bobby pin, pen cap or paper clip to firmly press and hold the button on the reader for 20 seconds.
- After 20 seconds, release the button and wait 10 seconds.
- Press the button again to turn the reader on and observe any lights on the reader.
If the reader lights turn on, you’re all set. If the lights don’t turn on, try again and make sure to firmly press and hold the reader’s button for a full 20 seconds.
My Reader keeps disconnecting
You reader shouldn’t have any issues staying connected, but here are a few quick tricks to help get you back up and running right away:
- Make sure Bluetooth is turned on from your device settings. If it’s on, try turning it off and back on.
- Make sure your reader is within ~3 meters of your device. Beyond that distance, the BLE connection will be out of range and become disconnected. You’ll also want to double check for bluetooth interference, check out this Apple resource for more information.
- Double check your reader is fully charged.
- If you are using a dock for your reader, plug the dock’s power cord into a grounded outlet.
- Delete and reinstall the Square app. If you’ve recently accepted payments while in Offline Mode and haven’t uploaded them, don’t delete and reinstall the app or you’ll lose these transactions. Connect your mobile device to the Internet to complete these payments before deleting the app.
- Check your internet connection. A weak connection can cause your reader to disconnect.
- Turn your mobile device off and back on.
Keep in mind your reader will enter sleep mode after 2 hours of inactivity, simply press the power button once to wake your reader back up.
