Dubai's Roads and Transport Authority operates one of the world's largest city-scale mobility systems, serving 802 million passenger journeys annually across metro, bus, tram, marine transport, taxis, and parking.

Existing validators, fare rules, and clearing systems could not change. The digital nol Card had to be operationally identical to the physical card — across approximately 2 million Samsung devices in the UAE that RTA does not control.

OnBoard™ Transit delivered the digital nol Card to Samsung Wallet — supporting all card types, fare products, and entitlement rules across 60+ device models. At every gate and validator, the digital card is indistinguishable from the physical card. Beyond the gate, each phone became a service terminal: commuters can top up physical cards, purchase passes, and migrate to mobile.
