On a dealer visit or at a customs check the product reaches your hands and something feels off: the print is slightly different, the packaging slightly loose, the price too good. At that point all you hold is an impression, and you cannot act on an impression.
The classic route is to take a sample and send it to a laboratory. The result arrives days later; meanwhile the product goes on selling and the other side says "you have no evidence". And they are right.
A reading decides on the spot
The signature applied to the product is invisible to the eye but read in seconds with a reader. The answer is one of three: the signature is there and matches, the signature is there but is not the expected one, there is no signature. Each calls for a different action, and each goes on record.
What turns suspicion into a case is not the measurement but the record of it.
What the record must carry
- Time and place of the reading — so nobody can say "we were not there".
- Who read it — so the chain of responsibility is not broken.
- Result and number of readings — one reading may be a device fault, three are not.
- A photograph where possible — the state of the packaging that day stays on file.
Is the laboratory still needed?
If legal proceedings follow, yes. But the field reading decides which sample goes to the laboratory. Instead of suspecting a hundred products and sending all of them, you send three based on the reading. Cost falls, time shortens, and the file gets stronger.
Who keeps the record
The person who runs into a suspect product is usually not the person who will decide about it. Field staff report the finding; someone on the brand side makes the call. That gap is where most cases are lost: the finding is described over the phone, a photograph lands in a chat, and two weeks later nobody knows where the product is.
So the moment of reading has to produce a record of its own. Which code, where, by whom, and with what result — once all four are recorded, a finding becomes a file. A finding without a file is also of no use in a legal process.
Do you seize the product
The riskiest decision made in the field is seizing goods. Get it wrong and you damage a commercial relationship; don't make it and a suspect product stays on the market. What works in practice is splitting the decision in two: halting sales is not the same as recalling stock, and the first can be decided far more quickly.
Halting sales is reversible. If the investigation shows the product is genuine, sales resume and nobody is harmed. That is why the decision taken in the moment of suspicion should be the reversible one.
What a single finding tells you
A single counterfeit is rarely a single counterfeit. What matters is less the item itself than the batch and the channel it came through. Once the code is read, you already hold both; the finding widens from one product to a distribution route.
What is valuable in the field is not the product itself but the batch and the channel it came through.
