In one embodiment, the present invention provides a method and communication device with an emulated mag stripe capability. Information is transmitted in the mag stripe data indicating that the communication device has chip capability as well. This information is used by a server on the back-end (acquirer, issuer, network) to take advantage of that chip capability. For example, additional fields can be used for security measures and communication over the telecommunications network with the device can be performed to provide a more secure communication with a terminal. In one embodiment, the additional information is provided in the service code, using a unique 3 digit code other than 2xx.
