The integration of different transport accounts owned by the same person (e.g. their rail, subway and electric scooter accounts) is certainly a technical challenge. But one that the Open Transport initiative believe can be overcome, especially if common standards such as open APIs are used.
But technology isn’t the only barrier to overcome. Complete transport account interoperability also needs transport providers to accept they are just part of the complete customer journey.
It also requires different industries such as public transport, transport technology & MaaS platform vendors and even airlines & car parking apps to integrate and work together for the benefit of the customer. Leading to the swifter and easier implementation of an end-to-end Mobility-as-a-Service (MaaS ) transport ecosystem.
