WebWhat is the maximum distance that an RFID tag can be used effectively? —Name withheld. ———. With standard ultrahigh-frequency (UHF) systems, tags can be read from approximately 30 feet under ideal conditions. I have seen a passive UHF tag read from a distance of more than 300 feet, by Mojix 's STAR system, which uses highly sensitive ...

From How Far Away Can RFID Tags Be Read? - RFID JOURNAL
Web29 nov. 2024 · Far-range UHF RFID tags are able to be read from as far away as 12 meters when using tags that are passive to RFID. Active tags can reach distances that extend to 100 meters or greater. The frequency of operation for UHF RFID tags canvary from 300 MHz up to 3 GHz. UHF tags are among the most susceptible to interference. Web9 feb. 2014 · I've successfully gotten it to detect the tag, but only at a distance of about 3-4 cm when the tag is oriented parallel to the antenna. According to my limited research, the HF band allows read ranges of between 10 cm and 1 m for passive tags, depending on factors like antenna size, tag size and orientation, and transceiver power. Web13 feb. 2024 · You can set a delay (e.g. delay(2000)) after reading the (end of tag).A delay of (say) 2 seconds will allow the user to move the card far enough away from the reader. Note that delay is a blocking command which might not suit your purposes, in which case you could be looking at using the millis count to activate/deactivate the Serial.read. greenway west ashley
