Calypso Light Application Certification - SELP

Oct 2018

Low cost card, high security level

Calypso Light Application -CLAP- offers an ideal solution for low-cost and high-volume contactless cards production. For public transport, events, access control and many other applications, avoid magnetic stripes, barcode or QR-code, proprietary contactless tickets: take advantage of a fully secure and standardized contactless portable object with CLAP.
CLAP is a simplified Calypso Operating System which uses a subset of the Calypso rev3.1, with the same cryptography and security. It can be embedded in small components, paper or soft plastic, which allows it to be sold in automatic vending machines. CLAP has been designed by CNA to answer to operator needs, with a straight and fruitful cooperation with manufacturers in a dedicated CNA working group.

It is the perfect solution for the anonymous user. Unlike the magnetic ticket it makes use of contactless as the Calypso card, thus lowering maintenance costs, and unlike the memory contactless ticket, being a subset of Calypso rev3.1, it allows for greater and quicker integration with existing Calypso card systems. Its level of security and durability allows networks to approach anonymous users like never before.
