  • Publication number: 20250005565
    Abstract: A secure element for providing electronic second-type tokens, and includes an electronic first-type token having a monetary value. The secure element is configured to: generate an electronic second-type token based on the electronic first-type token, wherein the monetary value of the generated electronic second-type token is equal to the monetary value of the electronic first-type token; split the generated electronic second-type token into two or more electronic second-type tokens, a split electronic second-type token of the split electronic second-type tokens having the defined monetary value; and send to the second secure element the split electronic second-type token having the defined monetary value.

  • Publication number: 20230236815
    Abstract: Methods and devices are provided for installing and hiding applets onto smart cards devices. In a first step, a request for installing an instance of a first applet is received at the card device from an off-card entity. The request includes a first applet identifier. An applet instance is then installed with the first applet identifier in a registry of the card device's operating system. In a further step, a request for hiding the instance of the first applet identified by the first applet identifier is received at the card de-vice from the off-card entity. After receiving the hiding request, the smart card operating system finds the applet instance with the give applet identifier and hides it.

  • Patent number: 10175963
    Abstract: A method is provided for executing a code sequence on a security module. The code sequence comprises codes to be replaced and codes to be interpreted. A temporary replacement takes place of a respective code to be replaced by a partial code sequence that comprises at least one code having an interpretable code value. The replacement taking place is dependent on the code value of the code to be replaced. An interpretation of the codes to be interpreted in the code sequence and in the partial code sequence takes place with the aid of interpretation information for code values. During the replacement step, the partial code sequence for the code value of the code to be replaced is additionally produced in dependence on a piece of selection information.
