Airports concentrate every modern payments challenge: international travelers, currency conversion, time-pressured purchases, regulated retail, and high-margin food and beverage. The result is the densest deployment of contactless, biometric, and DCC (dynamic currency conversion) infrastructure in commercial retail.
Next-wave deployments fold payment into identity. Biometric boarding pilots increasingly link to wallet-stored travel credentials, with implications for duty-free purchase authorization and lounge access.
