hello,plz tell me what is the default data on smartcards.(smartcard unique number and whatelse..).what is the difference between SIM card and SmartCards other than physical size.what is the default data we find on SIM cards.thanks in advance...
Every smartcard compatiblie to ISO 7816/4 will provide a so called ATR(answer to reset) as the response to a reset. based on transmission protocol (T0/T1) theis ATR has to be interpreted difrent ways. a part of it anyway is called "Historical Bytes" which will provide the information set by the manufacturer in form of CategryIndicator, Card life cycle etc...
If you are in application level, you don't have to worry about this at all. depending on the API you use to access the cards you can get the ATR though (OCF, PC/SC, JSR268, ...) and ask your hw provider for the information of the relevance for you.
