I would like some information about using the sensitivity settings on an RFID reader for passive tags, as I have found very little written on the subject. How would I adjust the setting to reduce sensitivity, and why would this be done?
Typically, passive UHF RFID readers are shipped with the highest sensitivity setting in order to maximize read range and consistency. You can check your reader’s sensitivity setting by referring to the owner’s manual for the specific make and model. It is possible to reduce the sensitivity of a reader so as to reduce the read range. This is usually done to avoid stray reads from tags that are outside the area in which you want to capture data. You might turn down the sensitivity level of a reader at a dock door, for example, to avoid reading tags on items coming through a neighboring dock door.
