Occasionally RFID systems can miss tag reads or show unintended reads that keep integrators up at night; however, sometimes the fix is quite simple if you know what you are looking for. Learn how to stop the blame game from Klaus Schoeke, Vice President of Technical Sales and Support for FEIG Electronics, webinar recording on “Who Gets Blamed When RFID is Not Working” and how to reduce RFID errors when using “UHF” or “RAIN RFID” technology, which stands for radio-frequency identification and its connection to cloud servers for online data management. Some of the topics he will cover include:
- Dense-interrogator mode for anti-collision and multiplexing
- Reader and tag sensitivities
- Avoiding the blame game with simple troubleshooting
Dense-Interrogator Mode for Anti-Collision and Multiplexing
The quality of your dense-interrogator mode for anti-collision and multiplexing will depend on your reader. While you might assume that newer models are better for all scenarios, the reality is that some models are simply better than others for specific tasks.
When tested, certain readers are consistently slower when it came to the number of tags read per second. This complication is due to the reader switching between several antennae.
Another factor that can cause lag time or errors in scanning includes the number of readers scanning near each other in close proximity. Healthcare products have an especially high margin for RFID errors. Too many RFID antennas in close proximity can affect the scan quality.
Reader and Tag Sensitivities
The reader can play a huge part in the quality of each scan. Yet, tag sensitivities can also affect the way the RFID reader scans each tag. This can become a serious issue when dealing with technology such as contactless payment methods, automatic vehicle identifications and access control equipment.
According to FEIG Electronics, “On average, today’s tag technology is increasing almost 1 decibel in sensitivity per year, enabling ever-greater accuracy and tag performance.” Newer machines are almost always better at reducing reader and tag sensitivities, but certain models also outshine and outperform when it comes to RFID readers.
Other factors that can affect the mobile RFID readers’ sensitivity include the environment, reading range and tag density. The age of the tag also plays a huge role in the card reader’s ability to scan it effectively. A quality reader should be able to scan each tag in less than one second, regardless of the age of the tag.
