Protecting offline payment applications is hard as offline payment introduces specific risks relating to bearer instruments and double-spending. Crunchfish Digital Cash offline solution enables offline payment for 3rd party online payment services by offering a secure, isolated runtime and encrypted storage with rollback protection for all offline assets.
Offline payments introduce specific risks that need careful consideration. Since the offline assets reside in a bearer instrument that is in the control of a potential attacker, it is of paramount importance that the payment application takes the necessary precautions to protect the offline assets and any operation performed on them. There are multiple ways that a potential attacker can stage an attack that results in double-spending.

Protecting offline payment applications is hard, and existing mobile software protections are insufficient for offline payments. Although these protection mechanisms are better than nothing, they do not hold back attackers for long. Please refer to
"Crunchfish Digital Cash is the only offline payment solution for smartphones that is both secure and scalable. The security levels in external offline payments services can now be increased using Digital Cash technology and security features. The Digital Cash protector has already been presented and very well received by many key stakeholders in the Indian payment ecosystem as it augments the security for the offline payment services announced for UPI Lite and the Digital Rupee", says
