An expandable cellular phone (200) includes system for allowing the cellular phone (200) to physically mate with, and electronically link to, an independently functional auxiliary module (400). The system includes a contact face (309) on a backside of the expandable cellular phone (200) to mate to a corresponding back face (403) of the auxiliary module (400). The back face (309) of the expandable cellular phone (200) includes at least one electrical contact (215) at a location mirroring a location of a mating electrical contact (405) on the corresponding face (403) of the auxiliary module (400). Moreover, at least two locating points (303, 407) are provided on the back sides of both devices (200, 300), with each locating point (303) on one device (200) including a locating pin (307), and each corresponding locating point (407) on the other device (400) including a receptacle (409) for the locating pin (307). |
