Abstract: In some implementations, an identifier manager may receive, from a user device, a request for a virtual identifier, the request indicating an intended user for the virtual identifier and a permanent identifier to be associated with the virtual identifier. The identifier manager may receive, from the user device, an indication of a set of restrictions for the virtual identifier. The identifier manager may generate the virtual identifier in response to the request. The identifier manager may transmit, to an account manager, the virtual identifier for association with the permanent identifier and the set of restrictions. The identifier manager may determine a mobile receiving device based on the intended user. The identifier manager may verify a user of the mobile receiving device. The identifier manager may transmit, to an application executed by the mobile receiving device, the virtual identifier in response to verifying the user.

Abstract: In some implementations, a proxy device, configured to receive requests on behalf of a first card network, may receive a request to authorize an event. The request may include a virtual identifier that is associated with the first card network. The proxy device may map the virtual identifier to a permanent identifier that is associated with a second card network different from the first card network. The proxy device may replace the virtual identifier in the request with the permanent identifier in order to generate a detokenized request. The proxy device may transmit the detokenized request to the second card network for processing.
