QR codes consists of barcodes in two dimensions. Since their invention in 1994, Japan, the codes have brought much convenience 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 of the shop owners.
Moreover, QR codes replaced the process of manually entering long URLs of company 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.
And bringing your mobile phone everywhere indicates that there is no privacy of where you go. Data keeps track of every footprint.
