A first security element is for transmitting an electronic coin data set to a second security element. The electronic coin data set is registered in a coin register of a payment system. The method has the steps of: setting a status of the electronic coin data set from the security element to an inactive status; transmitting the electronic coin data set from the first security element to the second security element; checking whether a receipt confirmation from the second security element has been received in the first security element; and deleting the transmitted electronic coin data set if the checking step results in that the receipt confirmation has been obtained by the first security element. The aforementioned relates to a payment system, a coin register, a security element, and a terminal for transmitting electronic coin data sets.

Method, terminal, and coin register for transmitting electronic coin data sets

A method is provided for installing a security-relevant portion of an application made available by an application provider in a security element of a terminal. The terminal requests the application from the application provider and receives the application. Subsequently, the received security-relevant portion of the application is transmitted to a trustworthy instance administrating the security element. The trustworthy instance subsequently installs the security-relevant portion of the application in the security element.

Method for installing security-relevant applications in a security element of a terminal

A security element of a mobile device comprises a service-provider network subscription associated with a service provider. The security element is arranged such that the service-provider subscription is employable parallel to a user network subscription installed on the security element. A service associated with the service provider thus becomes utilizable on the basis of the service-provider subscription, independently of a user subscription that might be present on the same security element.
