Digital jewellery combines fashion and technology by embedding computer components like displays, microphones, and batteries into jewellery items. Prototypes include earrings with speakers, rings that flash to indicate incoming calls, and bracelets with small screens. Digital jewellery could replace keys, IDs, and payment cards by storing user information. Future versions may break cell phones into separate jewellery pieces that communicate wirelessly. While offering convenience, challenges remain around battery life and durability of embedding technology into accessories worn everyday.
