Systems and methods for authentication using radio frequency tags

A method for approving a requested operation from a secondary user of a resource that is controlled by a primary user, comprising:

• receiving, by a back end computer processor executing back end non-transient computer-readable computer program instructions and from a secondary user computer program that is executed by a secondary user mobile device associated with a secondary user, a requested operation involving a resource that is controlled by a primary user;
• receiving, by the back end non-transient computer-readable computer program instructions, a secondary user unique identifier from the secondary user computer program, wherein the secondary user computer program is configured to receive the secondary user unique identifier from a secondary user physical radio frequency (RF) identification tag associated with the secondary user by radio communication;
• authenticating, by the back end non-transient computer-readable computer program instructions, the secondary user by verifying that the secondary user unique identifier that was received from the secondary user physical RF identification tag matches an expected secondary user unique identifier for the secondary user physical RF identification tag;
• accessing, by the back end non-transient computer-readable computer program instructions, a database of approved operations;
• determining, by the back end non-transient computer-readable computer program instructions, that the requested operation is not a routine requested operation by comparing the requested operation to the database of approved operations;
• communicating, by the back end non-transient computer-readable computer program instructions, a request for approval of the requested operation to a primary user computer program executed by a primary user mobile device associated with the primary user;
• receiving, by the back end non-transient computer-readable computer program instructions, a primary user unique identifier from the primary user mobile device, wherein the primary user computer program is configured to receive the primary user unique identifier from a primary user physical RF identification tag associated with the primary user by radio communication;
• receiving, by the back end non-transient computer-readable computer program instructions, approval for the requested operation from the primary user computer program;
• authenticating, by the back end non-transient computer-readable computer program instructions, the primary user by verifying that the primary user unique identifier that was received from the primary user physical RF identification tag matches an expected primary user unique identifier for the primary user physical RF identification tag;
• enabling, by the back end non-transient computer-readable computer program instructions, the secondary user computer program to perform the requested operation, wherein the secondary user computer program is configured to perform the requested operation with the resource via the back end computer processor;
• and
• updating, by the back end non-transient computer-readable computer program instructions, the database of approved operations with the approved requested operation.
