Electronic cards have become the new method for unlocking doors. You can find them in practically any public building or hotel. Keys have been traded out for wired cards of plastic when it comes to unlocking and securing doorways. It makes entry into desired locations easier, but doesn’t that mean it also makes keycards vulnerable to hacking? Not exactly.
We know that pressing a card to an electronic reader is much easier than fumbling around with keys for seconds on end. Everyone who owns a keycard can be recorded in a larger system, keeping name and photo ID connected to the card number to know at all times who is granted access, and who is not. Every time a keycard is used, that information is stored in a monitoring system, so it is possible to look over successful and attempted entries into a building or room at any time.
For businesses, aside from heightened security, keycards can also save thousands of dollars by bypassing rekeying any doors because of a security breach. Instead, keycards can be wiped and reassigned if needed, or when an employee leaves the company. Most electronic access systems can also be hooked up to existing alarm systems, and send emails to authorized individuals whenever security is compromised.
The risk for electronic access sabotage is slim, and the advantages in keycards are numerous.
