1. A method for authenticating a customer to a vendor for a transaction involving goods or services, the method comprising:
providing a token, wherein the token is at least a part of a mobile entity, wherein the token is coupled to a secret being indicative for the identity of the customer, wherein at least a part of the mobile entity has a processing unit coupled to the token;
coupling the token with an access point by establishing a physical contact using a first communication channel between the token, the processing unit, and a point-of-sale terminal of the access point;
transferring the secret to the access point;
linking 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;
providing the authentication token to the vendor using the first communication channel; and
establishing 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.
