Abstract: Described herein are techniques for facilitating push provisioning of a user payment source into a user's digital wallet without the user having a physical card. The techniques allow an issuer to provide a button in an issuer's mobile application for the user to simply push the button to request that the payment source be imported into the user's digital pay wallet. In this way, the payment source information is “pushed” into the pay wallet. Using push provisioning, the user need not enter any physical card information. The described techniques generate a chain of trust that can be used to ensure that a user, through an issuer and using an encryption gateway, authorizes a token service provider to provision the payment source into the user's digital wallet.
