Enhance existing e-KTP chip card to support micro-payment feature
The usage of micro-payment cards have been increasing worldwide. The same condition also happens in Indonesia. It can be seen from the number of customer who have Flazz BCA, Mandiri e-toll card that keep increasing by the matter of time. And not so far from now, Indonesia government will implement a new citizen identity system that using a contactless, chip-based smart card. This system has a lot of good prospect, and one of them is by implementing a micro- payment feature into one of its feature. The card itself still has some free space that can be used for another application that is separated from the e-KTP main feature itself. To implement a micro-payment feature, the data structure should be changed so the new application can store needed information and also gathered needed information effectively. Therefore, a new data structure will be proposed and also a simple application to demonstrate the micro-payment feature will be created. In summary, it is possible to enhance the e-KTP card to support the micro-payment feature. But the data structure inside the card should be changed into the proposed one, so that the application will not interfere other application and the data flow will be more effective.
