There are a few aspects to consider in the implementation of RFID in the warehouse process- Reader/Receiver Sensitivity, Tag Type/Tag Strength, and warehouse environment/available space will significantly affect the implementation and how overall successful it will be.
The sensitivity at which the reader receives information back from the RFID Scan is important in warehousing environments- Too high and you are getting more unexpected assets in your capture. Too low, and the reader needs to be in very close proximity to the tag to read the ID.
In the real world, if you are scanning items, a barcode reader would only scan the barcode within the capture area of the scanner. However, the RFID reader receives all ID's within proximity of the read field. If the combined read strength of the tags and the reader are high, then you might capture more unexpected ID's.
Prep requires accuracy. Sometimes shorter read lengths allow for the user to operate with greater accuracy with other equipment is nearby the prep area. Meaning if most tags have a read capability, and you are in the middle of an aisle with gear three or four feet away (~1m), your chances of capturing unexpected reads is reduced.
If the tags have larger read lengths, consider the location where you prep items, so as not to capture more unexpected reads.
RFID functionality combines the ease to track every item and auto-return them from their specific job through the Free Scan In process and represents a large speed increase to batch capture the mass amounts of these assets. Tags with longer read distances might be considered more advantageous to capture quicker, without the need to be within a foot (0.3m) of the item.
