One Ticket, Every Journey: Decoding EN ISO 24014-1 and IFM Systems
Unlock the potential of EN ISO 24014-1. Discover how this standard defines Interoperable Fare Management (IFM) for seamless, multi-modal public transport ticketing.

What is EN ISO 24014-1?
EN ISO 24014-1 is the international standard titled “Public transport – Interoperable Fare Management System – Part 1: Architecture.” It provides the conceptual framework and technical reference architecture for creating Interoperable Fare Management (IFM) systems.
In modern public transport, passengers expect to move seamlessly between buses, metros, and trains—often operated by different companies—using a single smart card, smartphone, or banking card. EN ISO 24014-1 defines how these disparate systems “talk” to each other. It establishes the roles, security policies, and data flows necessary to ensure that a ticket bought from Operator A is recognized and validated by Operator B, and that the revenue is correctly distributed.
The Core Roles of IFM Architecture
The standard breaks down the complex ecosystem of electronic ticketing into distinct operational roles to ensure transparency and flexibility:
- Product Owner (PO): The entity that defines the fare rules and creates the ticket types (e.g., “Monthly Student Pass”).
- Service Provider (SP): The operator running the trains or buses where the product is used.
- Retailer: The entity selling the product or loading it onto the user’s media.
- Customer: The passenger using the service.
- Clearing House: The financial intermediary that calculates how much money is owed to each Service Provider based on the validated usage data.
Why It Matters for Smart Cities
Without EN ISO 24014-1, every transport operator would build a “walled garden” (proprietary system). This forces passengers to carry multiple cards for different travel modes. This standard is the backbone of MaaS (Mobility as a Service), enabling the integration of national rail networks with local municipal transit under a unified security management system.
Comparison: Proprietary vs. Interoperable Systems
| Feature | Closed Loop (Proprietary) | IFM System (EN ISO 24014-1) |
|---|---|---|
| Scope | Single Operator / Single City | Multi-Operator / National / Cross-Border |
| Media | Specific card issued by the operator | Any compliant media (Bank card, Phone, 3rd party card) |
| Revenue Distribution | Direct internal accounting | Automated via Clearing House |
| Flexibility | Low (Vendor Lock-in) | High (Modular roles and standardized interfaces) |
