The key is precisely centred by the special profile ridge structure, ensuring problem-free insertion of the DPI key. Keys guarantee maximum protection against copying. The system has three different safeguards that protect keys against being copied or tampered with:

• Managed protection
  EVVA or EVVA Partners only make keys for authorised individuals with required proof of entitlement, such as a security card.
• Legal protection
  Keys are only manufactured for sale by EVVA and specialist companies authorised by EVVA. What's more, EVVA protects against the unauthorised manufacturing of DPI keys by means of patented features on the key.
  The distinctive feature: "EVVA" can be seen written on the key profile. As the EVVA brand offers life-long protection, this profile also features life-long protection.
• Technical protection
  Keys have technical features that require specialised machines and a high level of expertise for their manufacture.
