As we move across the city, we can see that smart cards are used in various applications such as transport ticketing, micro-payment, access control, etc. Due to proprietary standards/protocols, each of this application requires a new smart card. What if there was a body or organization that standardizes these protocols? Would it not be great if we could use a single card for multiple applications? The answer is yes, and as we have seen in the previous blog, open standards for smart ticketing system helps the passengers to easily switch between public transports and use a single card for multiple applications. In this blog we will understand the importance and usage of CIPURSE™ open standards.

What is CIPURSE™?

CIPURSE™ is an open, international standard from Open Standard for Public Transport (OSPT) alliance for transport ticketing. It was developed to enable interoperability across secured, cost-effective and flexible multi-application schemes supporting fare collection. With these standards, transportation authorities don’t have to depend on one particular vendor for the entire system. They can enable cross-vendor system interoperability.

CIPURSE™ profiles:

CIPURSE™ offers different specifications for various levels of security and functionality. Based on these specifications, CIPURSE™ products can be classified under three profiles: L, S and T. The minimum number of applications, file types and user data supported by these profiles are pre-defined.

L-profile: This is a basic profile with minimum security and functionality. CIPURSE™ L profile compliant products just have one application in it. It is mainly used for limited use ticketing and other low-cost applications.  

S-profile: This is a mid-level profile that provides increased functionality and memory. It supports multiple applications and can be used for weekly or seasonal passes.

T-profile: This is a high-end profile that has maximum functionality, security and increased memory. It supports multiple applications and is used in long-term applications such as yearly passes, employee ID cards etc.

Now let us look at the CIPURSE™ certified products from Infineon which are compliant to L, S or T profiles with some additional features. They are in the form of contactless smart cards and can be used for public transport ticketing, micro-payments, authentication and access control.

With this, we can conclude that CIPURSE™ open standards promote interoperability and cross vendor neutrality. This allows users to use a single card for multiple applications simultaneously. Infineon provides a wide range of CIPURSE™ certified products that can be used in various applications like public transport ticketing, micro-payments, authentication, access control etc. It provides chips for paper or plastic tickets, for smart cards and ticket validators, and also for smartphones and wearables such as wristbands or fitness trackers.
