Secure access control starts with the reader
The reader at the door is the most visible part of an access control system — and one of its most critical security elements. Modern systems require readers based on secure, next‑generation technologies instead of outdated, easily copied UID (card serial number) technologies.
Today’s access control emphasizes strong security, reliable supply chains, easy maintenance, and sustainable device choices. The right reader strengthens system protection and supports long life span for your system.
What to look for in a modern reader?
Scalable and upgradable
Your reader should support multiple system requirements and work with both cards and mobile credentials to ensure future compatibility.
Secure, open technology
Open standard technology available from multiple suppliers is a better choice for someone who does not want to be dependent on one supplier only. For system security, the reader should support encrypted OSDPv2 communication.
Security key management that benefits the customer
Security keys define which cards each reader can read. It’s essential to know who controls these keys; otherwise switching vendors may be difficult even with open technologies.
Multi‑factor authentication
A PIN code significantly reduces the risk of misuse, since access requires both the card and the correct code stored in the system.
Durability and usability
Readers must withstand moisture, dirt, weather, and vandalism. High IP and IK ratings, accessible keypad features, and installation flexibility ensure reliability and user‑friendliness in all conditions.
Trusted manufacturer and supply chain
For critical infrastructure, the manufacturer’s security practices and supply chain transparency are key selection criteria.
Environmental responsibility and long lifespan
Choosing robust, updatable devices reduces environmental impact and supports cost efficiency. European-made readers comply with stringent environmental regulations.
Cardea — the new access control reader
Idesco’s Cardea brings clarity and high security to access control.
It supports multiple encryption methods, reads both cards and mobile IDs, and endures outdoor environments with IP67 protection and IK09–IK10 impact resistance. A replaceable keypad extends device lifetime, and European manufacturing ensures compliance with strict quality and environmental standards.
