The advent of digital disruption in lending has yielded many advantages for both borrowers and lenders. Simultaneously, it has also generated apprehensions over regulation and risks. Like conventional lending, digital lending should possess qualities such as userfriendliness, distinctiveness, resistance to tampering, and being untraceable. However, it is vital for it to possess the capability to endure assaults from digital adversaries and safeguard against breaches of data. Contemporary technologies substitutes clients’ sensitive information with randomised tokens and guarantees the distinctiveness of payments by employing a cryptographic function called a cryptogram. Nevertheless, attacks utilising substantial computational resources undermine the security of these functions. Quantum technology can offer safeguards against the limitless computational capabilities. This work showcases the capacity of quantum light to augment the security of common digital lending systems by generating quantum cryptograms that are virtually impervious to counterfeiting. Our technique is distinct from previous protocols in that it is not contingent upon the presence of reliable agents and authenticated channels, nor does it rely on longterm quantum storage. Considering the present technological advancements, this is not only feasible but also possesses the potential to usher in a new epoch of security augmented by quantum capabilities.
