Deutsche Telekom is hoping cities will sign up to a new white label service that enables citizens to access a range of services via an app or card.
The Germany-based operator unveiled its City Pass offering at Mobile World Congress on Monday (26 February), promising to replace "the numerous cards and memberships commonly found in wallets today".
City Pass is an open platform based on blockchain technology that gives end users the chance to manage the likes of swimming pool memberships, bicycle rental services and library accounts via a single account.
Companies who provide services can also sign up to City Pass and transact directly with consumers.
Deutsche Telekom said there was potential for cities to target business travellers and tourists, as well as residents.
From 2019, the operator said it also hopes to make official civil services, such as applications for identity cards available via City Pass.
No cities have signed up to the new offering, Deutsche Telekom confirmed.
“We want to make cities genuinely smart and not only connect data," said Markus Keller, Senior Vice President Corporate Innovation and responsible for Smart City at Deutsche Telekom.
"With City Pass, we address the varying needs of cities: we offer new digital services for citizens, business and tourists.
"In addition, we also streamline administrative processes.”
Earlier this month, Deutsche Telekom held onto its mantle as Europe's most valuable telecoms brand.
