Quantum computing is poised to significantly impact retail fiscalization, the process of ensuring transaction compliance and preventing VAT fraud. While the legal purpose of fiscalization remains, the underlying technical controls, particularly those relying on public-key cryptography like digital signatures and certificates, are vulnerable to quantum-capable attacks. Experts anticipate that this shift will necessitate a transition to post-quantum cryptography standards to maintain the integrity of transactions, device identities, secure data transmission, long-term archives, and consumer-facing verification methods like QR codes.
