How to initial pin number of java card by user

Question

Hello,
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?

Yes - the javascript will provide a quick response to the user without having to go to the server. However its probably a good idea to have a validation in the validation section that validates it before you insert/update/etc. People can turn off javascript in the browser, so a page validation is always a good idea - Now the reality is the way Apex is built a user can't really turn off javascript because most of the buttons invoke javascript to submit the page, but thats another story.
You would code your button to do a URL redirect instead of submit if you want to use the javascript. Like:
javascript:submit();Now I hardcoded a doSubmit('SUBMIT') which is what your button would do, but if you need different request values, you can make it a variable and do it like that:
javascript:submit('CREATE');
function submit(pRequest){
  if(check()){
    doSubmit(pRequest);
}The Oracle side would be something more like this (just pseudocode - read up on the utility packages):
  v_table := apex_util.string_to_table(:P1_SHUTTLE);
  if v_table.count > 10 then
    return(false);
  else
    return(true);
  end if;Arggg - meant string_to_table - not list_to_table
