Possibilities

We could refer to the readers of proximity as the substitute of the key and the lock or electronic replacement, product of the advance of technology, traditional security systems. So far, the most used method, and all know, is the conventional card reader, which has been instrumental in recent decades, however, is the time to give way to the new breed of card readers. The old magnetic strips have given way to chips, thanks to which it has been possible to multiply the functions of card that all readers know. New readers enable controlling and managing all aspects related to the access of people to an enclosure: elaborate schedules, giving new users high or low, programmed to react in a certain way in a given situation and even memorize the time at which a person performs an access. The sophistication that has become today’s technology in some fields in the safety systems, have left completely obsolete the antique readers card, since these upper proximity readers have succeeded them with great success. The biggest advantage of proximity with respect to its predecessor technology, lies in that is no longer necessary to insert your card into the device so that it can read it, but it is capable of doing so without coming into physical contact with her. Activation occurs when the card is presented at a certain distance from the reader.

Plastic cards that are used with these readers incorporate a laminated, and passive circuit which is responsible for activating the system. Obviously the cards left to operate at a specific distance of safety, in order to avoid firings by mistake. Generally, the minimum space that there must be between the card and the reader for this no longer has influence on the system, is 70 centimeters. These readers personnel are designed and manufactured counterfeit-proof. In addition, not necessary that they are visible for it to work.

If the user wants it, they can be placed in a zone safe, away from potential vandalism attacks, dirt and meteorological factors. Currently there are different readers of proximity, among which it is not difficult to find suitable for different requirements in access control. What to make of this technology something usual and indispensable in the coming years is without doubt, the myriad of different applications that is able to be introduced. If we add to this the fact that with the passing of the years, the advancement of nanotechnology will increase the storage capacity of the card, we find that security systems may have found a long-lived and valuable resource in these readers.
