RFID Reading Guide
By using your RFID reader correctly, you can count faster, with greater control and reliability.
Section 1
How Does RFID Technology Work?
The RFID reader uses radio frequency to receive information wirelessly from the tag.
Section 2 · The most critical topic
Isolated Counting Area
RFID can read through walls; nearby tags may also respond. The cleaner the counting area, the more reliable the result.
Correct Environment
False Read: 0Use a separate counting room whenever possible. If that is not possible, create an isolated area by separating only the products to be counted.
Incorrect Environment
False ReadIn non-isolated environments, nearby products may also be read. This risk increases especially at high power.
Counting-area preparation checklist
- Use a separate counting room whenever possible.
- If there is no separate room, create an isolated counting area.
- Move nearby products away and simplify the area.
- Use physical barriers when necessary.
- Ensure that only target products are in the counting area.
Section 3
Power Setting
Her zaman maksimum güç kullanmayın. Power arttıkça okuma menzili büyür, ama yanlış okuma riski de yükselir.
Section 4
Single-Shelf Reading
Slow, consistent scanning produces more accurate results. Move the reader continuously along the shelf.

Section 5
Box Counting
Do not read the box from the front only. Scan the front, right, back, and left sides methodically.
- Scan the front side slowly.
- Briefly scan along the right and left edges.
- Do not skip the back side.
- Check the count when reading is complete.
Section 6
Correct and Incorrect Use
The same device delivers much more reliable results with the right environment and movement.
Correct
- Correct power
- Isolated area
- 30-50 cm distance
- Slow scanning
- Continuous movement
Incorrect
- Maximum power
- Scanning too quickly
- Nearby shelves
- Stationary antenna
- Unnecessary repetition
Live field scenario
Real Counting in a Warehouse Aisle
Staff walk along the shelf, sweep the antenna toward the shelf face, and the terminal processes read tags instantly.

Best Practices
Core habits that improve counting quality.
Correct antenna angle
Move the reader toward the tag at a changing angle.
Correct power
Increase it as the area expands; do not use unnecessary power for close-range counting.
Isolated environment
Remove tags other than the target products from the counting area.
Single shelf counting
Proceed shelf by shelf; do not try to read different shelves at the same time.
Read from all four sides
Scan the front, right, back, and left sides in order.
Final check
At the end of counting, compare the expected quantity with the result in the system.
Section 9
Common Mistakes
These mistakes can make the counting result appear higher, lower, or duplicated.
×
Power too highMay cause tags on the adjacent shelf to be read.
×
Moving too quicklySome tags may be passed before they can respond.
×
Reading too close to a metal surfaceSignal reflection and shadowing may occur.
×
Staying in the same spotUnnecessary repetition and uneven reading.
×
Reading nearby shelvesThis is the most common issue in non-isolated areas.
×
Counting in a crowded environmentThe target product and surrounding products may be mixed up.
Congratulations
You are now ready to use your RFID reader correctly.
An isolated area, balanced power, slow scanning, and four-sided checking are the foundations of accurate counting.
