The Archon Card (Seattle-based startup) has developed an affordable line of luxury cards -- be it credit or gift cards. This will surely give you the opportunity to stand out and be different. The company has stainless steel cards, carbon fiber cards, gold-plated cards and more. Other possible uses would include high-end rewards and loyalty cards, sports season ticket cards (that could replace paper ticketing systems) and hotel cards.
People spend money everyday on accessorizing their phones, jewelry and cars; it would only make sense to accessorize their credit card as well. Plus, this enables you to feel luxurious with every purchase you make, from packs of gum and groceries to truly luxurious expenditures.
