Abstract
A method and apparatus for effecting user-initiated communications, such as payment transactions, between user-accessible data terminal equipment communicatingly linkable with a mobile telephone exchange and at least one service provider, wherein each user or subscriber has a service card that is uniquely associated with that system subscriber, preferably employs a dedicated network to which the mobile exchange is connected at one end of the network and the service provider is connected at another end. The user's identity is locally authenticated before a communications connection through the network is provided, and user access rights to particular services of the service provider are determined in a database at the service provider end of the network. The invention is particularly well suited to the use of a SIM-card in a GSM-network to provide secure communications in an environment demanding high data security.
