Revenue Protection for Railways (RPO)

⬡ Products

Boost revenues with real-time penalty fines.

Most travellers purchase a valid ticket, but some may try to avoid paying. To prevent this, rail networks have implemented Penalty Fare systems. If even a tiny percentage of passengers fail to pay for their tickets, it can result in substantial revenue loss. Train companies are responsible for protecting the interests of fare-paying passengers and safeguarding taxpayer investment in state-owned railways. Anyone caught trying to evade the full price of a train ticket will receive a Fixed Payment Notice (FPN).

A fully automated system is essential for maximising revenue through FPNs. Each additional FPN issued daily results in millions of annual revenue the railway would otherwise lose.

Revenue Protection Officers (RPOs) can now enjoy a more convenient and hassle-free experience thanks to Theta’s integration of digital technology. This means managing tickets and issuing fixed payment notices can be done quickly, whether on a train or at a station.

The ticket issuance and payment collecting devices have NFC antennas and can support various ticketing methods, making them suitable for the transportation industry. RPO agents can use compact Bluetooth printers to issue and print FPN receipts safely and efficiently instantly. All FPNs are synchronised to the back-end system, even if the tickets were issued offline.

The software makes it easy for the RPO to issue FPNs by guiding them through a simple process of selecting the type of fine with drop-down menus, after which they can continue checking the other passengers.
