The consuming ability in Asia has grown drastically and the financial core of the world is now diverting together with the cash flow. High buying power is usually accompanied by the use of credit cards as it serves as a convenient means of cash flow especially for purchasing of goods with high prices, as cash transaction in such cases will be very inconvenient. 
         [0005]    Electronic technology is more diversified as our technology progresses. Various electronic devices are normal in our daily lives now and serve as a very important medium for acquisition of information and communication. The use of card readers grow more popular as the use of credit cards in the Asian region grows. However, the convenience of credit cards comes with the offset of risk during trade activities, especially with the use of card readers, which is now the primary target of financial criminals. These criminals tend to manipulate the card readers or hack into the operating system in order to gain access of personal information for illegal profits. 
         [0006]    Please refer to  FIG. 1  for the block diagram of the card reader system.
