Travel Retail Norway (TRN) has introduced Bitcoin payment options for duty-free purchases at Oslo Airport, marking its first step into digital payments. The service is available for travelers using the Klikk & Hent system, which allows online ordering and in-store pickup. This Bitcoin payment solution is provided by Satoshi Consult and operates on the Lightning Network. Currently, the service is limited to the arrivals area at Oslo Airport, with potential plans to expand to other airports and payment scenarios in the future.
