Long Distance Read Error
•
Too great an identification zone can also cause problems for your site. Sometimes a reader can
transact with a tagged vehicle driving through an adjacent lane or down a nearby street.
•
To prevent this, try horizontal siting of the EPC Windshield Label. (see Emission Patterns, above)
•
In some instances, metal surfaces near the reader are skewing the reading area, causing the error.
•
Hanging your reader from above and aiming it straight downward can reduce such reflections
while also shortening the reading distance. This may also help protect your reader from
erroneously interrogating transponders outside of your preferred identification zone.
•
If the problem can’t be resolved by changing tag orientation or reader direction it is possible to
reduce the transmitting power of your reader.
