Internet + big data = better service

Old citizens receive life-transforming digital help via govt information program

These days, when people over 80 in Beijing take a bus, see a doctor or spend money, their activities are digitally tracked by the government, as part of an effort to improve services for the country's rapidly growing elderly population.

The data amassed with each swipe of the multi-purpose "Beijing Connect" old person's card goes into a massive database of the elderly in the capital. City authorities hope the information will enable them to better cope with their burgeoning population of over-60s, which already stands at 3 million.
