Criticism
Compared to other contactless smartcards in use, the data transmission of Yang Cheng Tong is criticized by commuters that it takes 1~2 seconds between the card and reader to complete the transaction, though the operator claims that the data communication only costs 0.5 seconds in its official site.
Moreover, there are insufficient facilities to refill the card value with cash. Currently there are only two Yang Cheng Tong customer service centers, a few 7-Eleven stores and a small number of Guangzhou Metro stations accepting cash for recharging value to Yang Cheng Tong card. Otherwise, a bank card is required for using automatic self-service add-value terminals located at each Guangzhou Metro station and in joint banks, McDonald's restaurants, car parks, etc.
An issue with the Guangzhou Yang Cheng Tong smart card is, however, that the system seems to be very old in terms of IT systems. It was first used in the late nineties of the twentieth century. That is why the card does not support fare integration with other modes of transport, e.g. when you do a trip with multiple interchanges between bus and metro, you will have to pay again at every transfer from one to another mode of transport.

Famous quotes containing the word criticism:
“It is ... pathetic to observe the complete lack of imagination on the part of certain employers and men and women of the upper-income levels, equally devoid of experience, equally glib with their criticism ... directed against workers, labor leaders, and other villains and personal devils who are the objects of their dart-throwing. Who doesn’t know the wealthy woman who fulminates against the “idle” workers who just won’t get out and hunt jobs?”
—Mary Barnett Gilson (1877–?)
“To be just, that is to say, to justify its existence, criticism should be partial, passionate and political, that is to say, written from an exclusive point of view, but a point of view that opens up the widest horizons.”
—Charles Baudelaire (1821–1867)
“I hold with the old-fashioned criticism that Browning is not really a poet, that he has all the gifts but the one needful and the pearls without the string; rather one should say raw nuggets and rough diamonds.”
—Gerard Manley Hopkins (1844–1889)
