Computer-based systems and methods involving biometric authentication aspects for handling exceptions, enabling deactivation and/or performing other functionality

A system comprising:

• a transaction card comprised of:
• substantially planar base material;
• one or more sensors disposed within the material and configured to receive biometric information of a card owner during a use of the transaction card for a transaction;
• data storage disposed within the material and comprising memory configured to store information representing biometric data of the card owner;
• and
• non-transitory computer readable media storing instructions that, when executed by at least one processor, cause the at least one processor to:
• instruct a computing device associated with the card owner to generate a first user interface having one or more interactive UI elements that enable the card owner to manage one or more features associated with the transaction card, wherein the one or more interactive UI elements are configured to allow the card owner to enable a biometric-activated control of the transaction card based on the biometric information collected via a device associated with the transaction card or the card owner;
• and
• determine, in connection with the transaction associated with a vendor that the one or more sensors of the transaction card are biometrically-active based on an operation status of the biometric-activated control.
