GPK (Gemplus Public Key)
Cards
Product Sheet
A portable and secure
solution to access on-line services in Intranet and Internet architectures.
Would You Accept a Transaction Unsigned?
The replacement of paper documents such as purchase orders, generic forms, checks and
contracts by electronic documents leads to the critical replacement of handwritten
signature by an electronic trustable signature. This can only be achieved using smart
cards and public key security schemes. The digital signature is a vital component of all
applications such as Internet, corporate MIS transactions, e-commerce, home-banking,
identity, health care services... This is why Gemplus is bringing you its public key card
technology through its GPK card range.
The GPK4000 is suitable for most Internet Services,
including:
- Secure Web Server Access (SSL)
- e-mail (S-MIME)
- Micropayment (MPCOS e-purse)
