One of the largest barriers preventing people from using QR codes is simply an awareness of the technology. According to recent ComScore figures, smartphones make up 32 per cent of the phones owned by adults in the U.K. This is significant because as more consumers use smartphones they are discovering QR codes. Google has recently seen an increase in searches about the technology. Although there has been very little research on the use of QR codes in the U.K., according to 3GVision, in Q4 of 2010, the U.K. was the seventh largest user of mobile barcodes in the world.
As consumers, we are constantly bombarded with so many messages that we are not interested in, or if we are, we rarely have the time to properly engage with them สร้าง qr code. As we become ever more reliant on electronic devices for our short-term memory, it is only natural that we would use QR codes to bookmark information for later consumption.
For brands, QR codes are a really cost effective way to provide more information and drive consumers online. QR codes are interactive by their very nature and allow engagement to be measured. Brands can gain insight from metrics such as unique user usage, when and where the code was seen and even the duration of the interaction.
QR codes can hold several hundred digits and function even if they are partially damaged. They are also omni-directional, which means they are readable from any direction, ensuring high speed scanning.
From a technical perspective QR codes have more advantages than other 2D barcodes. The most widely used type of 2D barcode is the Universal Product Code (UPC), the series of bars found on day-to-day products. UPCs have their limitations as they are only capable of storing up to 20 digits and can easily be corrupted. However, a large part of the successful adoption of UPCs is a result of corporate backing.
Many companies, including Metro, Tesco, Calvin Klein, eBay and P&G, are leveraging the advantages of QR codes for their brands. Laura Marriott, CEO of NeoMedia Technologies has identified that QR codes used in ‘publishing and retail has the most traction’ currently in the market.
2D barcodes have many disadvantages, which are currently hindering their adoption in the West. One of the largest issues is the standardisation of symbols and a move towards open standards. One of the reasons UPC has been so successful is simply because it is universal. With so many different code versions from ‘QR’ to Microsoft’s ‘Tag’, there is no standard reader. Therefore, a consumer has to download multiple readers in order to scan different codes.
Subsequently, the vast majority of mobile manufactures have resisted pre-installing QR code readers on their handsets. Consumers have to download the correct app to read the code. They then have to open the app each time to scan a code, which can take longer than typing in a URL.
Unless the consumer is aware of QR Codes, the code is enigmatic. There are ways around this, such as incorporating a logo within the design. It also requires a level of trust from the consumer, because scanning a code could quite easily activate malware. Obviously this is less of an issue when using codes from trusted sources.
QR codes or 2D barcodes in general are easily defrauded when used for payments or coupons. By simply taking a photo of the code, it can be reused. When a wallet or card goes missing, the user promptly becomes aware, but it is less obvious using a code. Andrew Churchill, Consultant for Security Technologies, Identity Management & Cybercrime, explains that ‘a way to prevent this would be to use a form of verification and dynamic codes that only function for a set amount of time.’
