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.

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.

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.

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.

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.

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.
