Barcode ticketing specification for public transport

Scope

This new work item aims at standardizing multi-modal ticketing with modular barcodes on smartphones and on paper tickets for mobility services.
The TS will be developed based on the business needs that should be described through uses cases and will take into account existing specifications from other organisations (ERA/UIC) and existing national (and local) barcode specifications for public transport, with the mid-term ambition to create a EN standard.
Specifications will address digital usages with modular barcodes on smartphones and the layout for electronically issued paper tickets.
This work can look at future convergence with NFC and Check-In Check-Out / Be-In Be-Out use-cases.

The scope of work will address the following key areas for representing a barcode ticket:
• the “container” layout: the dataset / datasets defining the contracts (incl. encoding used) : structured barcode data contents.
• how the container is secured/sealed : security elements, including digital signatures with encrypted seals and decryption keys (including for issuer – online or counter - and ticket control), anti-cloning mechanisms as key cryptography, based on an appropriate and certified security infrastructure
• the public key exchange mechanisms
• how to comply with the privacy rules and GDPR requirements

The work will also include :
• Modularity to allow the combination of interoperable and local barcode data coding between transport modes
• The possibility to feed data exchange mechanisms for ticket-check and annotation of additional information to a ticket

Specifications developed in relation to 2D barcodes shall refer to ISO/IEC 24778 (AZTEC) and/or ISO/IEC 18004 (QR code) and shall ensure interoperability and backward compatibility with ISO/IEC 15438 (PDF417) for some specific use-cases.

The work will not include :
- Personal modes of operation
