Encoding and verifying RFID labels: what equipment do you need?
Short answer
Encoding writes each item’s data into the chip; verifying reads it back and checks it against the print. An encoder like the ADA RF-300 prints and encodes up to 500 pieces per minute, and the RF-500 verifies with an RFID reader and a 1D/2D scanner.
What goes into the chip
Each item’s identification data, usually in the EPC and USER memory of the UHF chip. A reader picks them up at a distance and without line of sight.
Where the data comes from
From an Excel or CSV file, from the barcode or QR already printed on the label, or by reading the chip’s own identifier (TID). You can also design in BarTender and the machine prints and encodes with that data.
How it is verified
A second station re-reads the chip and scans the printed code; if they do not match, the piece is marked defective. That way every label that ships is correctly written and printed.
The full setup
An encoder with unwinder and rewinder, a thermal transfer printer, an RFID reader, a 1D/2D scanner and the software tying it together. Printum integrates those pieces with your system.
