Claim 11:
12. A communication system, comprising:
a token, wherein the token is at least a part of a mobile entity, and wherein the token is coupled to a secret being indicative for the identity of a customer in a transaction for goods or services from a vendor, wherein at least a part of the mobile entity has a processing unit coupled to the token;
an access point, configured to be coupleable to the token by establishing a physical contact such that the secret can be transferred to the access point using a first communication channel between the token, the processing unit, and a point-of-sale terminal of the access point,, wherein the access point is coupled to a processor, and wherein the processor is configured to link the secret with a location information of the access point, wherein an authentication token comprises the secret and the location information, the authentication token being indicative for the identity and the location of the customer;
an authentication unit of the vendor, configured to receive the authentication token via the first communication channel; and
a second communication channel between the customer and the vendor via the processing unit of the mobile entity to a processor of the access point, from the processor of the access point to the point-of-sale terminal of the access point, and from the point-of sale terminal of the access point to the vendor via a communication network, wherein the second communication channel is not location referenced and the second communication channel is for executing the transaction with the point-of-sale terminal after completing the location referenced authentication with the authentication token via the first communication channel, and wherein a bandwidth of the second communication channel is larger than a bandwidth of the first communication channel.
