Security card

Security cards or security notes are proof of ownership for the buyer of a locking system or a protected individual lock .

The security card is intended to ensure that duplicate keys are only given to the owner or administrator of the lock cylinder . However, the security card is not proof that the keys are protected against imitation by means of an industrial property right (patent or trademark protection).

The security card is issued by the manufacturer or the license partner (key shop). If a security card or security certificate is lost, a replacement card can usually be issued. A corresponding blocking note must then be made in the locking system documentation, and replacement cards are often not issued for individual locks.

A process has become established in the industry in which an order form for ordering keys is created using the embossed digits on the security card. In the past, security notes were sent by post to the manufacturer with the order and sent back with the delivery or the corresponding invoice. Methods using security checks and signatures are also known. Electronic features ( chip card or magnetic strip ) are also read from the security card using the appropriate hardware, so that orders for locking systems can be placed online.
