I want to create Android Mobile Payment application using Java Card. I find the example and tutorial from the internet and I found the Java Card Applet Developer’s Guide and another example. After I read those files and examples, Most of them set pin with assign the fixed value into the code. So, I want to know there is any way to set the pin code by user dynamically.
Moreover, I have one more question. I would like to store the credit card information into secure element on Android Phone. Which APDU command do I need to use ? WRITE BINARY or WRITE RECORD?
