A method comprising:

• providing, to a user, a temporary card comprising a circuitry configured to deactivate the temporary card at an end of a temporary use during a pre-defined time period that the user is travelling, including a start date and an expiration date corresponding to the time period that the user is travelling;
• managing, by at least one computer or server, operation of the temporary card, including:
• communicating, by the at least one computer or server, with an app resident on a computing device associated with the user;
• instructing the app to pair the temporary card with the computing device after a first authentication;
• providing instructions, by the at least one computer or server, to the app for the app to generate one or more graphical user interfaces (GUIs) configured to display:
• first interactive GUI elements, allowing a first user-selection of first criteria including:
• the pre-defined time period of approved use and/or at least one location or geographic region of approved use;
• and
• second interactive GUI elements, allowing a second user-selection of second criteria related to approval or verification of the temporary card of the purchase transactions or establishment of a physical interaction between the computing device and the temporary card;
• activating or deactivating the temporary card based on the first user-selection of the first criteria;
• and
• facilitating an establishment of a physical interaction between the computing device and the temporary card based on the second user-selection of the second criteria.
