However, it will make a huge difference in your long-term system performance. It may require that you find new RFID tags or change the reader or tag orientation. Identify and create the RFID systems’ environmental conditions and test your system performance to optimize your work. After you have consulted with a representative from an RFID manufacturer about which tag is best for your application, you should decide which tag and reader orientation work best, too. On-site testing is crucialĮnvironmental conditions, change the performance of an RFID system. Misusing surface-specific tags can cause read range to drop from 20 feet to inches or the RFID reader could miss reading the tag entirely. The same is true for off-metal tags on metal surfaces. However, on-metal tags on other surfaces perform poorly. On-metal tags combat the interference and use the metal surface to amplify tag performance. Metal causes conventional RFID tags’ performance to suffer. The applications for RFID are nearly endless, but RFID surface placement falls into two categories: on-metal and off-metal. There is a big difference between on-metal and off-metal RFID tags Maintaining RFID tag and RFID reader orientation will ensure you get a proper reading each time.Ī disoriented tag will drop the read range from feet to inches.ģ.
Like with your RFID reader, you should decide early on what orientation best fits your application. RFID tag manufacturers should provide placement directions to optimize each tag. RFID tag position mattersīoth passive and active RFID tags are directional. The orientation of your device could determine how you orient your RFID tags and vice versa. Turn your device 90 degrees and the read distance could drop to just a few inches. An RFID system can read tags from up to 20 feet. Once you have decided, it is crucial you maintain a consistent reader orientation or your read distance will drop significantly. We recommend deciding early on whether you plan to use your RFID reader vertically or horizontally. While RFID readers can be circular and multi-directional, a full-performance read cannot take place unless the device and tag are aligned.
The tags, which are also directional, require properly oriented scanners to fully function. RFID readers send out ultra-high frequency directional waves to talk with RFID tags. Scanning barcodes on rugged mobile computers, tablets Here are four things you should know about UHF RFID. However, the emergence of advanced RFID readers and low-cost RFID tags, which come in hundreds of shapes and sizes for any application, mean the RFID industry is booming. It has seen mainstream use in manufacturing, automatic toll systems, and more for decades. It’s quickly surpassing LF, low frequency, and HF, high frequency, RFID as the go-to asset management and tracking technology. UHF, or ultra-high frequency, RFID is the fastest growing segment of the growing RFID market. Active tags utilize batteries to boost their power output. RFID readers, like the optional UHF RFID reader inside the Mesa 2 Rugged Tablet, transmit signals to read and write data on RFID tags. RFID, short for radio-frequency identification, uses electromagnetic frequencies to communicate between RFID readers and RFID tags. Wireless technology is changing the way companies manage and track assets and inserting itself into the fast-moving internet of things movement – but it can sometimes seem finicky.
