THE UNIQUE RFID CASTLE - A SELF-ASSEMBLY KIT
The most popular electronic locks are controlled from the keypad - entering the appropriate password will block or unblock the protected circuit. Much more comfortable and that is why contactless locks are becoming more and more popular. They operate based on the RFID system, in which there are no contact elements (keyboards), and the keys are special transponders in the form of cards or key rings. The code is read out wirelessly using radio waves. Such keys require only the proximity of the receiving antenna of the lock. It is also interesting that transponders do not require battery power, because energy is also supplied to them wirelessly.
The device is particularly recommended in alarm and surveillance systems
