This technology uses radio frequency waves to enable the process.Ī typical RFID-enabled devices includes a tag, an antenna, and the reading device. How Does It Work?Īn RFID tag reader can identify an object, gather preprogrammed data about it, and enter this data into a database without requiring no (or almost no) human input. While this technology can be slightly more expensive than traditional barcodes, an RFID credit card reader can offer many advantages over barcodes for businesses. This technology is used in many modern objects including passports, luggage, home appliances, pet tags, smart cards, heart patient devices, car locks, toll booths, retail item tags, and even in spacecraft. Rather, a USB RFID reader can identify a tag up to 300 feet away.
However, unlike barcodes, these gadgets don’t need to scan a tag or be in sight of a tag. The technology works similarly to barcode identification. That’s why they are alternatively called RFID tag reader gadgets. These devices use radio frequencies to gather information from a tag. The acronym stands for radio frequency identification device.
