UHF is the most predominate of the two due to its long-read ranges. Within the world of RFID material handling there are two predominate technologies used HF and UHF. This table compares frequency bands and the technology used in each one: Chart comparing different real-time locating system technology. Higher frequencies promise a stronger signal and one that reads at a farther distance but is more sensitive to disruption from various materials 1. This is important for environments that may require RFID tags to interact with these substances. Low frequency usually has a weaker signal and a shorter read distance but is less affected by disruptors to radio frequencies (such as liquid or metals). These terms refer to the wavelengths of the frequency – low frequency has longer wavelengths, which increase and shorten as the frequency gets higher.įrequencies determine the strength and distance of the signal. RFID functions on radio wave frequencies, which are measured within frequency bands: low frequency, high frequency, ultra-high frequency (such as RAIN RFID) and super-high frequency. To see how RFID compares to other tracking technologies, see this article. We’ve been in the industry a long time and provide a basic overview of RFID below so that you can begin your journey towards efficiency, lower operation costs, security and more. IT Asset tracking in offices and schoolsĬompanies and organizations have increasingly adopted this technology for the above benefits, and have additionally realized the advantage it provides in reacting to unforeseen events such as COVID-19. Subsequently, using RFID or another tracking technology is essential to remaining competitive in today’s market.Eliminated cost of replacing lost or stolen items.After all, it’s ability to track item location and data provide endless benefits: There are additional things you can do to protect yourself from being tracked.ĪirTags don't store any location data or history, and communication history through the Find My app is end-to-end encrypted, according to Apple.RFID, or Radio Frequency Identification, is a technology we’re sure you’ve heard of by now. These features include a shortened time period in which a nonowner is notified of an AirTag's presence, improved warning sounds, a tracker detection app for Android devices and an alert at setup stating that the AirTag is linked to your Apple ID and is designed to enable law enforcement to request identifying information on the AirTag's owner. State officials also warned the public that AirTags can be abused and misused as a tool for stalking others.Īpple has since added a few extra security features to help prevent its AirTags from being used maliciously. However, reports emerged earlier this year that the devices were being used for stalking. "AirTag is designed to track items, not people," Wolfman-Estrada said during the Apple spring event when the company introduced AirTags. Carolyn Wolfman-Estrada, an engineer at Apple, said safety features are in place that discourage unwanted tracking. Apple is big on privacy, and the company says people can participate in the Find My network without having to share their location with anyone, including Apple.
