Digital pass verification systems and methods

A server to distribute first instructions on a network, the server comprising:

• at least one storage device including second instructions;
• and
• at least one processor to execute the second instructions to transmit the first instructions over the network, the first instructions, when executed, to cause a mobile device carried by a person to at least:
• access a user identification associated with the person;
• access, via input on a display of the mobile device from the person, a result of a diagnostic test performed on a sample gathered from the person using a test kit, the test kit to test for an infectious disease;
• access one or more images from a camera of the mobile device while the person aligns a test kit code on the test kit in view of the camera, the test kit code being a machine-readable code;
• detect and interpret the test kit code from the one or more images to obtain a test kit identification associated with the test kit;
• display the result on the display of the mobile device;
• generate an interface including the user identification, the test kit identification, and an indicator, the indicator generated in response to the result for the infectious disease being negative;
• store the interface in a memory of the mobile device;
• determine, at a first time, a first number of days since the diagnostic test;
• compare the first number of days to a threshold number of days;
• display the interface on the display in response to the first number of days being less than the threshold number of days to enable the person to gain entry into a location;
• determine, at a second time, a second number of days since the diagnostic test;
• compare the second number of days to the threshold number of days;
• and
• delete the interface in response to the second number of days being greater than the threshold number of days.
