Patent attributes
Methods and systems are presented for facilitating sharing of tokens among different funding accounts linked to a digital wallet application to improve the computer resource efficiency of the mobile device. When a first funding account is linked to the digital wallet application is received, a token management system may determine whether a set of tokens have already been issued and stored on the mobile device for another related funding account. The token management system may cause a token service provider server to abort generating additional tokens for the first funding account. Instead, the token management system may modify characteristics of one or more of the set of tokens existed on the mobile device, to enable the one or more existing tokens to be usable in electronic payment transactions in association with the first funding account or the second funding account.
