Double-encrypted RFID electronic keys – Solution to the problem of uncontrolled proliferation of electronic keys !!! These contactless RFID chips are multi-layered cryptography protected by a double individual dynamic password. The keys are with a specialized Lesi cryptographic protocol and CANNOT be copied! The double-encrypted RFID key has a 256-bit code and operates at 125kHz, combining two keys into one. The double-encrypted key works with double-encrypted systems (BKU617), single-encrypted systems (BKU317, BKU517), standard systems (BKU417, BKU217, and other systems operating at 125 kHz). So again you only carry one key that will work to many different systems/doors.

Another outstanding advantage is that these encrypted RFID electronic keys can be transferred from one BulKey system to another BulKey system, using specialized software and a data cable. If the system is standard (not encrypted), it will be carried as a standard key. The encrypted key can be transferred by specialized software from a regular system to an encrypted system, and then its encrypted part is also transferred, i.e. it will function seamlessly in the new system as an encrypted chip!

They are distinguished by high quality and very good range. As can be seen from the pictures, all RFID chips are the same in appearance, but LESI keys are distinguished by the larger size of the antenna, which significantly increases the range of operation. Information can be printed/engraved on them. Ergonomic and comfortable to wear.

Works with Bulkey BKU617 and all other BulKey RFID systems! Systems working with this type of electronic keys can use three types of readers – for built-in, panel, hidden installation, depending on the place of application of the locking system. The fact that contactless readers can read the electronic chip code from a distance of 1 cm to 12 cm (typically between 2 and 5 cm) allows them to be hidden by being installed behind non-magnetic barriers such as glass, wood or others.

An advantage of the built-in contactless reader, patented by LESI, is that it can be installed directly in the door or cash register, regardless of the material of which the door is made, and at the same time the reader cannot be stolen.
