    Abstract: A system is provided for processing offline digital resource transfers using a hardware device based cryptographic application. In particular, the system may comprise a portable hardware device or chip that have a cryptographic application and key stored thereon. The hardware chip may further store information about a digital resource associated with the user. A user may, through a user computing device, initiate a digital resource transfer by retrieving a data record associated with the digital resource transfer from a terminal. The user computing device may then access the cryptographic application stored on the hardware chip, where the cryptographic application may use the cryptographic key to digitally sign the data record. In this way, the system provides a secure and efficient way to process offline digital resource transfers.
