Claims15
A secure element for use in an electronic payment transaction system, the secure element comprising a processor and an interface, wherein at least one offline generated token of the secure element comprises a monetary value and a token generation history;
- the secure element being adapted to enter a token replacement mode of the secure element for replacing the at least one offline generated token of the secure element, if a threshold value is exceeded;
- in the token replacement mode the secure element transmitting the at least one offline generated token via the interface and receiving at least one replacement token via the interface, wherein a monetary value transmitted is identical with the monetary value received;
- wherein
- the token replacement mode is an offline token replacement mode;
- the threshold value is compared with a token history value of the at least one offline generated token;
- the at least one offline generated token token is transmitted to a local special secure element of the electronic payment transaction system;
- and
- the at least one replacement token is received from the local special secure element.
A method in a secure element of an electronic payment transaction system, the method comprising the following steps:
- entering a token replacement mode of the secure element for replacing at least one offline generated token of the secure element, if a threshold value is exceeded, the at least one offline generated token comprises at least a monetary value and a token generation history;
- transmitting the at least one offline generated token;
- and
- receiving at least one replacement token, wherein a monetary value transmitted is identical with the monetary value received;
- wherein
- the threshold value is compared with a token history value of the at least one token;
- the token replacement mode is an offline token replacement mode;
- the at least one offline generated token token is transmitted to a local special secure element of the electronic payment transaction system;
- and
- the at least one replacement token is received from the local special secure element.
A special secure element for use in an electronic payment transaction system, the special secure element comprising a processor and an interface, wherein the special secure element is adapted to
- receive at least one offline generated token from a local secure element via the interface, the at least one offline generated token comprising a monetary value and a token generation history;
- and
- transmit at least one token to the local secure element via the interface;
- wherein
- the special secure element stores a plurality of vault tokens for use in an offline token replacement process;
- and
- the special secure element is adapted to perform the offline token replacement process, wherein a monetary value transmitted is identical with the monetary value received.
