Cash-to-digital and digital-to-cash conversion remains relevant in European markets where significant portions of the population maintain a preference for cash even as digital payment infrastructure expands. Aircash was founded in Zagreb in 2015 to build infrastructure that bridges those payment forms, providing services that let consumers move between cash and digital wallets through retail networks across Croatia and the broader Balkan region. The platform combines a digital wallet, a Visa prepaid card, and a network of retail cash-in and cash-out points that gives users practical alternatives to bank-mediated digital payments. Aircash has expanded its product range and geographic coverage across Southeastern European markets, building a position that addresses both the digital and cash-preference segments of the market simultaneously. The Balkan markets have lower formal banking penetration than Western Europe and a continuing significant role for cash in everyday commerce, making the cash-bridge model commercially viable in ways that pure digital wallets struggle to achieve in those markets. In the broader European fintech landscape, Aircash represents the regional infrastructure that addresses payment preferences specific to its market — a model that requires depth in retail partnerships and operational logistics rather than the technical scale that international payment platforms emphasise.
