Contactless double-encrypted RFID system with electromagnetic lock type Bolt BKB100, works with up to 999 pieces of double-encrypted RFID key Tag. Suitable for locking homes and offices with high security; for aluminum and metal doors. The door is opened from the outside by an electronic key and from the inside by a button. The electromagnetic lock is a BulKeay BKB100 model – extremely strong and suitable for armored, aluminum, PVC, wooden, metal and thin profile doors !!! Locks with a single spike with Ф16 mm, 15 mm depth. The lock is invisible, both on the outside and on the inside.

In response to the uncontrolled copying of chips and the desire of our customers to stop this, we designed and built encrypted systems. The BKU617 is a dual encrypted non-contact RFID system that works with special encrypted 125kHz ASK LESI2 keys. These chips have 256 bit code and are extremely good value for money and protect the key from copying through the copiers. The advantage of our technology is that copy-encrypted keys can also be used on standard non-encrypted systems, allowing one key to be used for many different devices!

The encrypted chip can be transmitted from one Bulkey system to another BulKey system through specialized software and a data cable. If the system is plain (unencrypted), it will be ported as a simple key. It can be transferred from an ordinary system to an encrypted system, then its encrypted part is also transferred and it will function seamlessly in the new system!

The BKU617 is controlled by a master card, which adjusts the operation of the system and records, deletes, prohibits electronic chips. The device can also be controlled via PC, smartphone, remote via SMS or via the Internet (purchased separately). The method of programming, recording, deletion, status of a specific key, the total number of keys in the system are described in the detailed instructions attached to the product and according to a patented by LESI algorithm.

The system is micro-sized, has many protections, memory for events. It has extremely easy installation, maintenance and programming. Consumer electronic keys depend on the individual needs of each client. You can view and order the details of the double encrypted chips HERE!
