1. A smart card comprising:

  • a processing circuit;

    a memory, wherein the memory contains a protected object, wherein the protected object initially cannot be utilized in its protected state by the processing circuit within the smart card;

    an activity detector, wherein the activity detector receives a signal that describes a planned activity of a person who is in physical possession of the smart card;

    an activity analyzer, wherein the activity analyzer evaluates features of the planned activity, and wherein, in response to the activity analyzer determining that a predefined risk associated with the planned activity exceeds a predetermined value, the activity analyzer;

    issues an instruction to the person who is in physical possession of the smart card to provide a biomarker to a biosensor that is physically contained within the smart card, wherein the biosensor is a camera, and wherein the biomarker is a digital photograph of the person who is in physical possession of the smart card; and

    receives, from the biosensor, real-time biometric data for the person who is in physical possession of the smart card;

    a receiving device, wherein the receiving device receives a security object;

    a blending logic, wherein the blending logic combines the real-time biometric data with the security object to generate a hybrid security object;

    a conversion logic, wherein the conversion logic uses the hybrid security object to convert the received protected object into a usable object that can be utilized by the processing circuit within the smart card;

    a photo memory, wherein the photo memory comprises a previous digital photograph of a person who is authorized to be in physical possession of the smart card, wherein the previous digital photograph was taken before the biomarker was taken;

    a comparison logic, wherein the comparison logic compares the previous digital photograph and the biomarker;

    a blocking logic, wherein the blocking logic prevents the conversion logic from creating the usable object in response to the previous digital photograph failing to match the biomarker;

    a matrix barcode generator, wherein the matrix barcode generator generates a matrix barcode that contains payment information, identification information, and authorization information for the person who is in physical possession of the smart card; and

    a display, wherein the display displays the matrix barcode on the smart card.
