It used to be that in order to keep track of something, one had to use their eyes. Once it was out of sight, it was practically lost. But as society evolved, so did the tools used by humanity. Nowadays, keeping track of something is as easy as slapping a tag on it and using a CSL RFID reader connected, wirelessly or otherwise, to a computer.
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.
Tagged chips can also be use to keep track of living things. Pet owners often implant their animals with chips in order to make keeping track of them much easier and also to find them easily should they get lost. Animals can also be tagged while in zoos or other amusement parks, to keep track of them and to make sure that they remain in their respective enclosures.
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.
Now, simply picking a reader is easy. There are many that are currently on the market. Picking the right one is the key.
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 has changed the world, sometimes for the better, sometimes not. But, mostly for the better. There are those whose lives will be negatively impacted as technology continues to progress, but there are many more who will benefit greatly.
