Radio Frecuency Identification Analysis

Most people are struggling to track items that may be left behind or stolen at some point in time or at some point. In order to combat this general accident, radio frequency identification, also known as RFID, is useful. This technology can be used anywhere from clothing labels to pet collars. Radio frequency identification can transmit data and automatically track marked objects. Each tag contains a unique number, and the processor reads the tag, allowing the technician to identify the tag and return the lost item to the legal owner.

Radio identification (RFID) radio identification (RFID) is a generic name for technologies that automatically recognize people and objects using radio waves. There are several identification methods, but the most common is to store the serial number identifying a person or thing on a microchip connected to the antenna. Other information (chip and antenna are collectively called RFID transponder) or RFID tag). The antenna allows the chip to transmit identification information to the reader.

WaltonChain was named after Charlie Walton, inventor of RFID (Radio Frequency Identification). RFID reads a small amount of information, or "tags" stored on the chip using radio waves, as well as how the barcode scanner picks the strips and the gap between them using light. Normally you can save about 2,000 characters on the label. This is usually sufficient for version control, raw tracking, tax code, etc. RFID is not a new technology - it was originally proposed in the 1940's and widely adopted in the 1970's - but despite that era it still has advantages. You do not need a line of sight like a barcode or QR code; the tag can read at a few feet away and you can scan the shipment being transported. The reading time is usually several tens of milliseconds (Barcode and QR code are north of 500 milliseconds)

Before comparing the barcode system with RFID, let's briefly introduce what RFID is. RFID (Radio Frequency Identification) is an automatic identification method that needs to use a line of sight for communication as a barcode system and uses radio which is radio wave communication between RFID reader and chiplet tag. Barcode system and RFID have the same technology called automatic recognition to identify objects, people, animals. Both have implemented a data collection method to reduce human errors and improve work efficiency. Wyld (2006) stated that there are many differences, even though the barcode system and RFID come from the same technology family.
