Before loading an applet, you must to do an authentication with the Card Manager on Smartcard. In order to do the authentication, you have to know the card issuer keys. There is a limit number of attempt to authenticate. Usually this number is 10. If you exceed this limit, the card will block. Once you do a successfully authentication this limit is reset.
