The USB credit card offers a lot of space for photorealistic digital printing. The corners are rounded and there is an eyelet for attaching a mobile phone strap or a mini carabiner. The USB interface is protected by the plastic body and is simply folded out if necessary. The USB credit card is very flat. The thickness in the interface area is approx. 3 mm. Only about 2 mm in the edge area. This means that the USB credit card has enough space in your wallet or shirt pocket.
