The morning commute can be slow, regardless of how you make it. For those using public transportation, there are several merit and demerit which you have to consider. The Shanghai subway system which is the biggest subway system on earth has made a great step by adding a convenience to the trip. The addition was as a result of the new move which would let customers use quick response (QR) codes to pay for a trip through UnionPay or Alipay. You may be surprised that the largest subway system on earth is in Shanghai, but this is because the system usually carries more users than the entire population of Hong Kong on daily basis, that makes it clear the volume the system sees on daily basis. This is why it is crucial to speed up lines so as to make things faster.
QR code readers are being used at the 389 metro stations and a minimum of two gates have the “scan, pay and pass” functionality at the east station. The number would likely increase and more payment providers would be introduced especially if the early ones prove to be successful.
The first thing which the user will have to do is to download the app, and from there it is very easy as the name implies. The user can then decide to pay for the trip before setting out, or the system will deduct the fee from the relevant account automatically. When you have more than one billion people in a place like china, there is high tendency that you will come across lots of line and anything that will keep the line moving would be highly welcomed. The QR codes work very well for speeding up lines. Mobile payments have also been able to trade on their convenience value, after all you need to do is to scan a code and then touch a machine with a smartphone on several occasion. So the introduction of this system has created convenience in places like Shanghai subway system because it would speed up the flow of traffic and also get users to where they are going within a short period of time.
Although some robust security would be put in place because this is a hacker honeypot, however it would move traffic faster through and make it easier to move early in the morning.
