QR code is a technology from the 1990s, which is proving to be very useful during the pandemic. In the mid-90s, Japan invented the code to track components in car production.
This code can hold up to 2,500 numeric characters, a massive number when compared to the standard barcodes of 43.
Therefore, QR code is utterly useful as it can hold much information, including names, locations and websites addresses.
Uses of QR code amid the pandemic
Ever since the pandemic, many pubs and restaurants moved quickly to install QR code systems.
“We saw how five years of a future technology was accelerating at a pace of five months,” says Mr Schatzberg. Mr Schatzberg owns renowned restaurant such as Duke’s and Big Daddy’s in New York.
Besides, pharmacies are also using this code. In the US, CVS is offering touch-free payments through a partnership with PayPal and Venmo at 8,200 stores. Customers simply scan the code during checkout through their PayPal or Venmo mobile app, which is contactless and very convenient. However, if the customer is not the user for these two apps, they can pay using their debit and credit cards, or bank account. The QR code checkout process, then pulls out fund needed for the purchase from the customer’s account, similar to online transaction.
QR codes aid in contact-tracing
Public health agencies also see value in taking advantage of QR codes in the process of contact-tracing. For instance, through the NHS in the UK, designated venues in certain sectors have a legal requirement to display NHS QR code posters. This is because customers with the NHS Covid-19 app can “check-in” using this option as an alternative to provide their contact details to the venue.
Countries such as Australia, Singapore and South Korea also use this technology in contact-tracing.
Pay via QR codes
Scan food items and subsequently pay for them through QR codes is also trending these days. Granbango utilzes this technology and named it as a “checkout-free technology”. Granbango’s technology allows grocery shoppers to take items off the shelf and leave without paying for them at the cashier. Instead, shoppers scan their unique QR code at a kiosk after they have finished shopping.
