Quick response (QR) code payments
QR (abbreviation of “quick response”) codes have many uses and are often found in advertising, on product labels and what seem to be the most random places. Not everyone knows they can be used to pay for things too. It works through certain banking apps where your cards are already associated, and other apps by stores and providers where your card details can be connected.
To use an American example of in-store payments through a QR code, Walmart customers can use the Walmart Pay app, where their payment method is connected, and simply pay in store by scanning a QR code at checkout through the app.
In all cases, you have to aim the camera carefully to match the indicators on your phone screen before the app can scan the code. Some people report feeling this is a hassle, especially since you have first open the relevant app before you can start scanning.
QR codes take a few steps to open up an app on your phone, then a basic amount of precision to scan, which for some people can feel like a barrier.
Some e-commerce businesses use QR codes at their website checkout as an alternative to manually entering card details. For card-not-present transactions, this is more secure because your phone, that your card details are securely connected to, confirms you are the owner of the card – and because you’re not typing your unencrypted card details on a device screen.
