Device Compatibility Questions
My device doesn’t support BLE (Bluetooth Low Energy). Can I use the reader?
Devices without BLE aren’t currently supported with the reader.
Can I connect my reader to multiple devices at the same time?
The reader can be used with multiple devices, but it only connects with one device at a time. To connect your reader to another device, make sure to disconnect it from its current device. To do so, visit your in-app Settings > tap Card Readers > select your reader from the list > tap “Forget this Reader.”
You can also disconnect the reader by holding down the button on the reader for 6-15 seconds, until you see solid red lights.
Can I use this reader if my business is mobile?
Yes, just make sure you have a strong Wi-Fi or mobile data connection to process payments and that your reader is fully charged before use.
Can I use any USB cable to charge the reader?
Yes, you can use any standard micro-USB to USB cable, but the reader comes with one for this purpose. While we can only guarantee that our charger is supported, many sellers have had success charging with other cables.
Settings and Pairing Questions
How do I connect the reader to my mobile device?
You can connect your reader wirelessly or by using the included USB cable to plug directly into the hardware hub of the Square Stand. Keep in mind your device needs to have an internet connection to pair your reader, as Offline Mode is not available in the UK.
How do I pair my reader to a new device?
You can connect your reader to any device that supports BLE bluetooth connections. Remember, you’ll need to forget the reader from your old device before you attempt to pair your reader with a new device. If you have any trouble connecting your reader to a new device, check out our troubleshooting steps.
I’d like to connect my reader to the hardware hub of my Square Stand, but the three USB hubs are being used by other devices. Can I use a splitter?
We don’t officially support splitters or third-party USB hubs. We recommend connecting the reader wirelessly to your iPad via Bluetooth LE.
How do I turn the reader on and off?
To power it on, push the button on the reader. Once it’s on, you don’t need to worry about turning off the reader. The reader will automatically go into sleep mode when not in use for 2 hours to save battery.

Payment Questions
How do I take a contactless payment?
It’s easy! Watch this video to learn how:
What are contactless payments, and how are they different from NFC?
Contactless payments describe the act of paying without touching anything. NFC (Near-Field Communications) is a technology that allows for contactless payments. Using radio frequency, NFC allows devices (e.g. smartphones) to wirelessly communicate at close range to do things like process payments. Apple Pay and Google Pay are both forms of NFC and types of contactless payments.
Are contactless payments secure?
Yes, they’re just as secure as accepting chip cards. In some cases because of additional verification methods (like Touch ID with Apple Pay), contactless payments can be even more secure. Learn more in Square’s comprehensive guide to Apple Pay.
How long does it take to process a chip card?
Chip card payments require additional security steps to transfer and verify chip data. It can take around 6-7 seconds to complete a chip card transaction when it’s inserted into the reader’s EMV card slot.
Do I leave the chip card in the reader’s chip card slot while taking a payment?
Yes, you’ll need to leave the chip card in the reader until the transaction is complete. You’ll get a confirmation message in the app and see 4 green lights on your reader when it’s time to remove the card.
Can I take test contactless payments with the reader?
Not currently, but you can practice taking contactless payments by completing a £1 sale and immediately processing a refund.
Can I use the reader while my mobile device is connected to other Bluetooth devices?
Yes, you can connect to other devices without impacting your connection to the Square reader.
