Transit
Open loop transit solutions, entailing both a transit
application and an EMV payment application on a single contactless
or dual-interface smartcard, represent an optimal environment for
MULTOS.
Applications present on a MULTOS or MULTOS step/one card operate
entirely independent of each other throughout their respective
lifecycles. Owners of the applications remain responsible for the
provisioning of their respective applications and are assured that
individual applications are unable to interfere, or otherwise
access data, of other applications co-residing on the
smartcard.
Application provisioning
MULTOS applications are loaded to chips in secure packets known
as application load units (ALUs). The use of ALUs precludes the
need for secure transmission. As a result, dedicated lines and HSMs
are not required for the remote loading of applications. This
facilitates loading of the transit application on a bank-issued
card at kiosks, which may be located, for example, at stations or
passenger terminals.
Control over card content
During the application loading process, a file referred to as an
application load certificate (ALC) must accompany the ALU. ALCs are
specific to both the application and the card. In this way, the
owner(s) of the application and issuer of the card itself are
assured of the mix of applications capable of being present on the
smartcard at any time throughout its lifecycle.
Operating security
Distinct operating environments for each application resident on
a MULTOS card ensure that applications are completely independent
of each other. The providers of the payment and transit application
are therefore assured that application-specific data and variables
can not be compromised and are protected entirely within their own
firewalls.
MULTOS offers the ability to effectively bridge the gap that may
exist between transit operators and financial issuers. The MULTOS
framework assures that the interests of all parties, including
those of the cardholders, are protected to the highest degree. No
other operating system offers an equivalent mix of control and
flexibility. When it comes to open loop transit solutions, MULTOS
is secure synergy.
