Proximity Cards, Keyrings and Bracelets

Cards, keyrings and bracelets are used in proximity access control systems, replacing conventional keys. All you have to do is bring the card close to the reader so that you can access the area.

Each of these identifiers carries a unique code that must be registered in the system, either by swiping the card or entering the identifier manually if it is printed. For this, it will be necessary to have a master card or access the programming.

The advantages of this system is the comfort of opening the door with a small gesture and without contact, ideal for people with reduced mobility. Also, cards, key rings and bracelets cannot be copied like regular keys, which adds extra security.

You will mainly find two types of cards / keychains / bracelets, which are: MIFARE (13.56MHz) and EM (125KHz). Before purchasing the identifiers, you must know the technology used by the reader, whether it is MIFARE or EM, and acquire the corresponding one; otherwise the card will not work.
