connecting to Smart Cards

[rigidigital]

Could a picaxe and a keypad be interfaced with
a smartcard to store data ? Like I found a site with smartcard connectors --> http://www.mouser.com/catalog/627/1048.PDF

I noticed elwhere that usb stick is possible. So just was curious about the card.

The answer is probably yes, but it depends upon what exactly the "Smart Card" is. Simple cards are no more complex than I2C Eeprom in a flat-pack. Those which are PICmicro/AVR + I2C Eeprom will either need programming with a suitable interface between PICAXE and embedded Eeprom or any pre-programmed protocol would need to be implemented. Smarter cards have a simple low-level interface but a more complex higher level protocol and a 'file system' of sorts.

Well, you should be able to read and write a simple EEPROM SmartCard through I2C. I wanted to do this but I didn't find the time to play around.

There is a similar project here that read smartcards <A href='http://www.serasidis.gr/circuits/telecard_reader/telecardreader.htm' Target=_Blank>External Web Link</a>. Maybe that will give you some hints.

you need to be carefull with them some can be just an i2c eeprom, but there are some with a pic or an avr inside as well then you have some that just shift out a 128bit or 256bit serial number
