To pay, simply scan the Payconiq QR Code, which can either be printed (invoice, receipt, sticker on the cash register) or displayed on a screen (phone, tablet, specific point-of-sale screen or your computer screen for e-commerce purchases) through the phone’s camera and your Payconiq App. The payment details will be displayed on the screen, at which point you can confirm the transaction with your PIN or fingerprint. The payment is made.
