A smart card is a card made of plastic and embedded with an integrated circuit (IC). It can have either a memory IC or a microcontroller unit IC (MCU). In the case of the former, the smart card will be able to only store and delete data, whereas in the case of the latter, the smart card will be able to process the data that is stored on the IC. A smart card may also be referred to as an IC card or a chip card. Smart cards offer higher security features than the traditional magnetic stripe cards and they are used across a variety of applications, some of which include payment, transit, and government ID.The Smart Card market in China is one of the fastest-growing Smart Card markets. Although
currently the majority of the growth is derived from the Telecom sector, other high-growth sectors such as the Banking, Financial Services and Insurance (BFSI) sector, the Government sector and the Healthcare sector are expected to make significant contributions to this market. The market is expected to witness an improvement in its growth rate and post a CAGR of 14.07 percent for the period 2011–2015.
