A QR code consists of barcodes in two dimensions, which gives it the capacity to hold more data. Since its invention in 1994, Japan, much convenience has been brought to our social lives.

Pros:

• Alipay is a convenience-oriented application descended from the new technology. Chinese people typically like to pay for their items simply by scanning the QR codes provided by the shop owners.

• Moreover, in occasions where copy-and-paste is not available, QR codes have replaced the process of manually entering long URLs of companies’ websites. In this way, the amount of visitors of their digital Ads has been potentially increased.

Cons:

• QR codes require a mobile device with a camera and connection to internet.

• In places with conventions of scanning QR codes, you face the risk of being rejected by some restaurants that only have online order options.

• Bringing your mobile phone everywhere indicates that there is no privacy of your journey. Mobile data or connection to any Wi-Fi keeps track of every footprint.

In conclusion, although there are risks of using QR codes, they are avoidable as long as QR codes are not over-popularized in a country.
