V.Smile V-Link

The V.Smile V-Link is an accessory that works only with the Cyber Pocket, PC Pal, V.Motion systems, and a few of the newer V.Smiles. It allows the user to track their progress by keeping the accessory plugged into the Game Console where it automatically tracks a child's progress and scores. When plugging the V.Link into a PC's USB port, it auto connects to a secure website where the child can see how they rank against all V.Smile players also using V-Link. As children play more of their Smartridges and master more skills, they are rewarded with online bonus games that are "unlocked" by their progress.
