Initially implemented by Koleje Dolnośląskie, the system allows passengers to verify their identity and student discount eligibility during the ticket purchase process. This eliminates the need to present physical ID cards or student credentials to conductors. The digital tickets function offline, which assists travelers in areas with poor internet connectivity. Following this implementation, Łódzka Kolej Aglomeracyjna (ŁKA) announced it would also adopt the system starting August 17. Similar to the Koleje Dolnośląskie model, ŁKA passengers using KOLEO can authenticate their identity and student discounts—including a 51 percent reduction—via the mobile app to streamline inspections and boarding. ## Timeline ### 2026-08-15: Łódzka Kolej Aglomeracyjna integrates mObywatel for digital identity verification Łódzka Kolej Aglomeracyjna passengers can now use the mObywatel app to verify identity and student discounts for tickets purchased via KOLEO, simplifying the inspection process. 9 sources. https://clstr.news/cluster/dzka-kolej-aglomeracyjna-integrates-mobywatel-for-digital-identity-verification ### 2026-08-10: Koleje Dolnośląskie and KOLEO integrate mObywatel for digital verification Koleje Dolnośląskie and KOLEO have integrated the mObywatel app to allow digital identity and student discount verification, simplifying ticket inspections for passengers in Poland. 2 sources. https://clstr.news/cluster/koleje-dolnolskie-and-koleo-integrate-mobywatel-for-digital-verification --- Cite as: Polish rail integration of mObywatel digital identity.
