Getting And Using An RFID Reader

By Ruth Fisher


Human society marches forward. Such is an undeniable fact of humanity. No matter what happens, war, famine, or disease, human society is always going to march forward. Progress is an inevitability of life. It can be resisted, it can be attacked. It can even be delayed. But it cannot be stopped. As such, it is important to keep up, to not get left behind. Industries and people who do not keep up get left in the dust. Consequently, it is important to have the tools necessary to navigate the new world. One such tool is the CSL RFID reader.

Radio frequency identification, or RFID as it is more commonly known, is a system for the wireless reading of information. This is done via the use of tags which store information which an RFID reader then identifies. A passive tag will have no power source of its own and will instead rely on taking energy from radio waves emitted by a reader. An active tag will have more range and will have a power source such as a battery.

Ultra high frequency, more commonly referred to as UHF, are the frequencies at which many of the most essential systems in the world operate. A lot of things like cell phone coverage, GPS, and even Wi-Fi all operate on UHF. Many RFID readers are tuned to ultra high frequencies.

RFID tags are used widely in for security purposes. Items embedded with an RFID tag will often go off if taken out in a store. Similarly, identification cards can often contain chips in them, especially if there are systems in place to deny entry to outsiders. A chipped card simply allows entry into such places. Similarly, casinos chips are often tagged to prevent theft.

RFID tags can also be used to track animals. Many pet owners will tag their fur babies, so that if they get lose, finding them becomes easier. Zoos will also tag their animals to make sure that they remain where they are supposed to be.

The applications of RFID technology are limitless, governed only by the imagination. The technology can make shopping at a physical location much easier. Items can be tagged with chips and instead of waiting in line at a counter, a customer can simply walk out, with RFID readers automatically reading both the chips and the credit or debit card of a customer and charging the latter the amount for the former. If shopping at a physical location does not completely fade away, it should be revolutionized. The technology can also be applied to health, as dust can be made that can be introduced into the human bloodstream to monitor overall bodily health. The main challenge to such technology is the fear that it applied to tracking animals can crossover and be applied to tracking people.

Like most devices, there are many RFID readers available on the market. As such, the trick is not picking one. The trick is picking the right one.

Like anything else, price should be considered. RFID readers can cost hundreds of dollars for even the cheapest variant. The investment is good, but it is still a considerable one. Some RFID readers will have to stay outdoors. As such finding a durable one is key. A weak one will break easily and necessitate another purchase.

Technology is great. Humans are great for advancing it so much. As tech advances, human society will change and advance with it.
