| 摘要 | Embodiments of the invention relate to payment cards and methods for making payment cards. In one embodiment, a card comprises a first layer and a second layer adjacent to the first layer. The second layer comprises a plurality of particles comprising metal, and the plurality of particles comprise at least about 15 volume % of the second layer. In another embodiment, a mixture is prepared comprising polymer and a plurality of particles comprising metal. The plurality of particles comprise at least about 15 volume % of the mixture. The mixture is pressed and an outer layer is applied. The mixture and outer layer are then cut to form the card. | ||
