Payment Questions
It’s easy! Watch this video to learn how.
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 (eg smartphones) to wirelessly communicate at close range to do things such as process payments. Apple Pay, Google Pay and Samsung Pay are both forms of NFC and types of contactless payments.

Square’s comprehensive guide to Apple Pay.
Chip and PIN card payments require additional security steps to transfer and verify chip data. It can take around 2 seconds to complete a chip and PIN card transaction when it’s inserted into the reader’s EMV card slot.

You must reconnect your device to the internet to upload those offline payments within 24 hours from the time you go offline.
