The traditional lock and key method of securing your premises has been around for thousands of years, but if keys are lost or stolen, your security is immediately compromised and there will inevitably be the cost and inconvenience of changing locks and re-issuing keys. Copies of keys can also be made which means that you may have a breach in your security without even realising it.
Electronic access control provides the most efficient and convenient way of securing your building, and means that you will never have to change a lock again. Tokens or swipe cards can be issued to allow legitimate access through controlled doors. However, lost or stolen tokens can simply be barred from the system such that they will no longer allow access to your property.
