A few days ago, I had a LinkedIn discussion with Richard Turrin on QR Codes and their relevance in today’s go-cashless world. A few commentators on the post felt QR codes were the thing of the post, and I had a different view. I believe, in a world that’s getting digitised in a hurry, QR code is what bridges the digital world with brick and mortar.
QR Codes have gone through ups and downs since they were first created in 1994 by Japan’s automobile industry. QR – stood for “Quick Response”. However, those were days when mobile phones were clunky and the user journeys weren’t as friction-free as the ones we have these days.
When a customer scanned a QR code, an app or a website would be launched on the mobile using EDGE or GPRS. Once the website came up, users would have to use the clunky interface to fill in relevant details. I guess, that was enough to kill the QR code – or so many thought at that time.
QR Codes are more efficient than Barcodes because they are able to hold more information than Barcodes. This is because, QR codes have a two dimensional layout, where as with Barcodes it is just a one dimensional horizontal layout. And purely from a marketing perspective, QR Codes can be customised with a firm’s brand on it, unlike bar codes.
Utility of QR Codes seem better than Barcodes. But are they safe to store our information? For example, can I store my bank card details in a QR code and claim it is more secure? It certainly is – atleast in most scenarios.
Credit card thefts and frauds come in different shapes and forms. Even in a contactless payment mode, account details are still transmitted to the point of sale (PoS) device. So if the PoS device is hacked, hackers can get hold of the customer’s payment details. If at the point of sale, there is an issue with the internet, the customer experience could be poor.
The other hiccup is the case of lost devices, as QR codes do not check for user identity. This can however be overcome by asking for biometric information from the user at the time of registering. It could also be a selfie of the user at registration. At the point of sale, the device using QR codes, may have to use some ways of identifying the user.
Since QR codes rely on Wi-Fi networks, a hacker could get into the network and overlay fake QR codes. And then there is this issue of different variations of QR codes released by different vendors. There needs to be standards for ease of use from a customer’s stand point.
Despite some of these downsides, what makes QR codes special?
- Expanding mobile internet and
- Smartphones adoption.
With better internet access and smartphone penetration, QR codes have become more common place in Asia. Smartphone penetration in China has risen to 63% and to 35% in Asia as a whole. In Latin America (Argentina), customers have taken to QR codes as it is a simple interface for the unbanked to perform digital transactions.
Pictures showing Alipay and WeChat QR codes in China and PayTM QR Codes in India have brought the concept back to life – in a big way. In India, PayTM are running campaigns to get millions of small and medium entreprises onto QR Codes. In Africa, firms like Dumapay are using QRCode to simplify the point of sale payments process. It has become easy for a roadside shop to accept payments using a QR code print out and no Point of Sale device.
Apart from payments, QR Codes can be used for several other interactions. They can be use for
- Offering discounts,
- Sending a pre-defined message,
- Sharing contact details
- Embedded pricing information
- Linking to marketing videos or pages
China has taken the use of QR codes to a whole new level, as observed in the picture below. A quick google search on China and QR Codes reveal some really cool use of this tool.
As QR Codes are versatile, most top apps like Pinterest, Snapchat, Wechat and device manufacturers like Xiaomi, Motorola, Samsung, Huawei all have inbuilt QR Code readers.
But in the wrong hands, QR Codes can be used to lead a customer to a malicious page and get hacked in the process. There is definitely caution needed when using QR Codes.
It may be hard for the west to embrace QR Codes like Asia, Latin America (in some parts) and even Africa. But several firms across the world are creating their own customised QR Codes to stay relevant. QR Codes may not have succeeded in the past and they may not be the future either. But they most certainly have a place in the present.
