Can QR codes be used for mobile payments, and how does that process work?

Generation of QR Code

Businesses generate a QR code that represents the transactional information. This information includes details like the transaction amount and other payment-specific data. The QR code can be static or dynamic. Static QR codes contain fixed information that remains the same every time it's scanned. Dynamic QR codes, on the other hand, can be updated after the code is generated, allowing businesses to track the scan in real-time and modify the transaction amount.

Scanning the QR Code

Customers scan the QR code using their smartphone's camera. Upon scanning, the customer is directed to a URL linked to the QR code.

Entering Payment Details

The website or app linked to the QR code will prompt the customer to enter their payment details. These details could include credit card numbers, or the customer could connect a mobile wallet such as Apple Pay or Google Pay to complete the transaction.

Confirmation of Payment

After entering the payment details, the customer confirms the transaction. Once confirmed, the payment is processed, and the customer receives a confirmation message.

Receipt of Payment

The business then receives the payment, completing the transaction. Some businesses may also send a receipt to the customer's email address for record-keeping.

This process is secure because the QR code does not contain the actual payment information. Instead, it provides a link to a secure payment gateway where the customer can safely enter their payment details. Furthermore, the use of HTTPS ensures that all data transferred during the transaction is encrypted, protecting it from interception.
