How long does the reader stay connected?

Square Reader (1st generation) will go into a low power state if it hasn’t taken a payment for awhile and will remain connected to your device for 8 hours. Any interaction with the reader through Point of Sale will wake it up from this low power state as long as the reader is within 3 metres of the device. The reader will power off completely after 8 hours of inactivity. After this point, you will need to press the button on the reader to reconnect.

Stay Connected is a feature built into Square Reader (2nd generation) to maintain connectivity, improve reliability, help save battery, and eliminate the need to press the power button to re-pair the reader after a period of inactivity.

Square Reader (2nd generation) will go into a low power state if it hasn’t taken a payment for awhile and will remain connected to your device for 30 days. Any interaction with the reader through the previously paired Point of Sale will wake it up as long as the reader is within 3 metres. of the device. The reader will power off completely after 30 days of inactivity. After this point, you will need to press the button on the reader to reconnect.

Note: Stay Connected only works if the Square Reader(s) have been paired to the device already. If the reader has never been paired to the device, you’ll need to go through the initial pairing process.

Payment Questions

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 practise 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.
