The invention claimed is: 1. A portable communications device comprising communication means for communicating with a second device over a first communication link, and identification means, separate from said communication means, said identification means arranged to independently provide information identifying said portable communications device, from said identification means to said second device by means of a second communication link, to enable a communication connection over said first communication link between said communication means and said second device. 2. A portable communications device as claimed in claim 1, wherein said identification means comprises a bar code and said second communication link comprises a bar code reader. 3. A portable communications device as claimed in claim 2, wherein the bar code is arranged on the exterior of the communications device. 4. A portable communications device as claimed in claim 2, wherein the bar code is arranged to be displayed on a display of the communications device. 5. A portable communications device as claimed in claim 1, wherein said identification means comprises a radio frequency tag and said second communication device comprises a radio frequency tag receiver. 6. A portable communications device as claimed in claim 1, wherein said identification means comprises a magnetic data carrying arrangement and said second communication link comprises a magnetic data reader. 7. A portable communications device as claimed in claim 6, wherein said magnetic data carrying arrangement comprises a magnetic strip. 8. A portable communications device as claimed in claim 1, wherein said information provided by said identification means comprises one or more of the following: identity of the device; address of the device when the communication means are used; and identity of the user. 9. A portable communications device as claimed in claim 1, wherein said second device is one of the following devices: point of sale device; ticket gate device; and information kiosk. 10. A portable communications device as claimed in claim 1, wherein said first communication link with said second device is a wireless link. 11.
