MULTOS is a multi-application smart card operating system, that enables a smart card to carry a variety of applications, from chip and pin application for payment to on-card biometric matching for secure ID and ePassport.
Application providers can retrieve and verify the public key certificate of an individual issuer's card, and encrypt their proprietary application code and confidential personalisation data using that card's unique public key.
Hundreds of millions of MULTOS smart cards have been issued by banks and governments all around the world, for projects ranging from contactless payment, Internet authentication and loyalty, to national identity with digital signature, ePassport with biometrics, health care and military base and network access control.
Static memory is persistent and transaction protection ensures the integrity of application's stored data.
A MULTOS chip is a stack machine, which makes use of this dynamic memory to pass parameters and perform calculations.
