DESFire card and JavaCard

Postby GraceGIRL » Mon Jan 23, 2017 3:56 am

When we use smatcard in our project, which one we should select?
For DESFire card:
    Need one reader to support it;
    Write the client application for it; (But the command are not popular known by developers)
    The price of DESFire card is about $2.5 per piece.
For JavaCard:
    Here are more reader can support it;
    If the function is same as DESFire, the JCOP 10 card is enough to use;
    That is only one thing to do: write the applet;
    And write the client application;
Is there any other thinking about these types of card?

Follow your requirement.
If the logic is complex, use javacard to implement your requirement.
If you only want to make an authenticate and read/write many data values (ID/Name/Address/etc...), use DESFire.
That is my idea.
sense and simplicity
