A contactless access card for the Em-Marine and Mifare standards, made of natural carbon. The face is edged with a carbon or steel frame. Inside the frame is a pattern in the shape of intercom #2 Model S in silver-plated or gold-plated nickel. The carbon and the nickel are covered with a layer of jewellery-grade resin.
A Mifare access card carries a UID and rewritable memory. When the memory cells are used as intended, the card is protected from copying, and the security level is higher. It is used on sites with stricter security requirements, in payment and access systems, and for working-time records.
An EM-Marine access card has its own internal number and 64 bytes of memory or more. The chip can be read and is not protected from copying. A site that uses it has a lower level of protection. These cards are widely used in residential complexes, private houses and office buildings.
