RFID And Pulling The World Into The Future

By Ruth Fisher


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.

RFID means radio frequency identification. It is a method by which a device, a reader, wirelessly scans information from a tag embedded with a chip. There are two types of tags, the passive and active. Passive tags rely on siphoning power from the radio waves of a reader, while an active tag will have its own power source such as a battery.

UHF means ultra high frequency. Most wireless communications operate on radio frequencies in some form of another, and uhf is the frequency at which many of the most necessary wireless systems operate on. Wi-Fi, mobile phone coverage, and GPS are among the systems which operate on an ultra high frequency.

Now, RFID tags have numerous security applications. In places where doors are automatically locked, like a hotel room, an RFID chipped card is pretty much the only way to open it. RFID tags can also be used in stores as items can be chipped to alert staff and security if someone tries to bring them out without paying for them.

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.

Picking an RFID reader is as easy as simply going out and buying one. Like any other piece of tech, the market is flooded with all kinds. A customer is practically spoiled for choice.

A reader should not cost too much, but it should not be cheap. Then again, cheap is not really an option for most tech, as even a low cost reader can cost hundreds of dollars. Remember the adage of you buy cheap, you buy twice. A reader should be durable. Especially if it is placed outside. The outside includes dangers like the weather and rowdy people.

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