Final Concept
We are able to make working prototypes for the necklace, bracelet, and keychain, and below is the necklace prototype showing the feature overview of our design. There are limitations working with the physical model, such as the size of the RFID sticker and the magnet strength, but we were able to test out our concept and have a clear idea of our final solution.
We also built CAD models of our final solution. The magnet caps can provide stronger connection, and we found a kind of micro RFID chip that is only 5*5mm and can fit perfectly into our design. These models represent what our ideal product would look and act like.
Renderings
Here are some final renderings of the design, the product can be coated with different colors so that users will have more options to choose from.
