Are Magnetic Card Swipe Locks Secure?03/28/2014 Back To Blog
You might think magnetic card swipe locks are old technology now since you have used them hundreds of times in hotels or even dormitories. Due to the overwhelming development of lock systems, these locks might seem as old fashioned these days but they are actually the first babies of the new high tech age and of electronic door locks. Easy to use and practical they are considered for years an easy solution for many doors but it's not accidental that they are not used for main entrances in either businesses or residences.
Why swipe cards are not appropriate for homes
When we first came across with the card swipe locks, we were all amazed by the new technology. Despite the fact that it was really brand new at that time, the minute we tried to enter our hotel room we got disappointed. The philosophy of these systems is to pass the card through the card reader and see the door opening. The reader reads the encoded data in the magnetic strip and grants access. Well, that would be great for our home,s we thought. No more dealing with lost house keys, no more lockouts!
These systems never became popular though as main security door locks of homes and companies. That is not accidental at all! The magnetic strip loses its properties and won't be read by the reader. In fact, the swipe card will easily lose its magnetic strengths for trivial reasons. It is equally sensitive with bank cards and perhaps even more. If you put them together with your ignition car key or other metallic objects, if it's damaged even slightly, it will lose its strengths. The reader will also get dusty and dirty and won't read the card. Consequently, you will not avoid a house or office lockout.
Although there have been improvements and some swipe cards would transmit radio signals to readers to allow access, they are still not popular for homes and businesses where the demands for high security are much higher. Nothing is accidental in this life, not even the magnitude of some lock types since we all seek the best when it comes to lock installation and our security.
