Abstract: An access management system comprises one or more databases and one or more computers. The one or more databases may store access data, accessor data, restriction data, and/or biometric data. The one or more computers may comprise an account identifier management computer, an authorization server computer, and/or an account management server computer. The account identifier management computer may generate account identifiers for physical or virtual cards. The cards may have interface-specific account identifiers. The authorization server computer may be communicatively coupled to an account access system that is used to obtain account identifiers as input. The authorization server computer may apply one or more restrictions to an account identifier. The account identifier management server computer may enable monitoring account activity and/or generate ephemeral phone numbers that can be used to authenticate callers to call recipients.

Abstract: An access management system includes a database configured to store access data including account identifiers and accessor identifiers, wherein the access data indicates particular accounts that have been accessed by particular accessors. The access management system also includes a computer system that receives a reservation request comprising an account identifier and an accessor identifier and determines whether the account identifier is included in the database. The computer system also determines, in response to the account identifier being present in the database, whether the access data correlates the account identifier to the accessor and authorizes the reservation of the one or more resources in the account by the accessor in response to the access data correlating the account identifier to the accessor.
