Hi,
   Thanks. That was exactly what I needed. A chip
with a boot-strap loader program on it.

   I still have some doubts ( elementary )

   1. Do these chips follow the ISO7816 interface ?
   2. Do I need any special hardware other than Smart
Card reader to load my programs into these chips.
   3. Are there any other smart card chips which
simply have boot-strap loaders for developing ones own
smart card OS.
   4. What is the typical cost of these chips,
development suite etc.,
   If any one of you has had some experience of
implementing a smart card OS ( preferably WfSC ) on
cards, I'd be grateful if you could tell me these
details.

Thank you,
kits
