Doy Eye style barter implant. Cant see a glove being a great idea and maybe the chips arent the best way to go but im not sure.
A series of eyes could be kinda cool. even one that is recycled like the Doy Eyes has been discussed with friends. Like the recycle eye the user has a keen eye for item quality and is able to negotiate a discount with vendors. Make it recyclable from materials the way you do currently with the doy eyes.
Thoughts?
