Frequently Asked Questions About RFID Technology

RFID technology is used all over the world for identification purposes. It can make identification processes easier, more convenient, and quicker. However, some people still have questions and concerns regarding this technology. This article is going to answer some of the most commonly asked questions about RFID technology.

What exactly is RFID? RFID, or radio frequency identification, refers to technologies that use radio waves to automatically identify something. The most common way RFID technology identifies something, typically a person or object, is to store information on an RFID tag. The tag is made up of a microchip and antenna, which allow the information to be transmitted to an RFID scanner. Through the scanner, the information stored on the tag can be read and processed.

Are barcodes and RFID chips the same? While both barcodes and RFID chips store information, they have different applications. In order to read a barcode, the scanner has to be able to physically read the barcode printed on the ID card or object. This requires the barcode to be oriented directly towards the scanner. Unfortunately, if the barcode is ripped, faded, or blurred, it cannot be read by ID readers. On the other hand, RFID chips don’t require line of sight. As long as the chip is within range of the nearby ID readers, the information can be read.

What’s the difference between active and passive RFID? Passive RFID systems are powered by the electromagnetic energy that is transmitted from the RFID reader. Passive RFID tags are commonly used instead of standard labels and can be utilized in access control, supply chain management, smart labels, and device tracking. Active RFID systems, on the other hand, use self-powered tags that constantly put out their own signal. These tags can be used to track the real-time location of a person or object. While active RFID tags are more expensive, they can provide a longer read range than passive tags.

Because of the benefits this technology can offer, RFID card readers are becoming increasingly common. In fact, a study done by Peerless Research Group in 2016 found that 38% of growing companies were planning on investing in RFID technology throughout the next 12 months. RFID chips can be used by ID readers in a variety of industries to make work processes more productive and efficient.
