How to choose the best counterfeit money detector
Reviewed on 1 September 2026 · By the Detectalia technical team
There is no universal «best detector»: there is the right one for your cash volume, the way you take payments and your counter space. These are the criteria that separate good equipment from a future problem — and our recommendation for each case.
The five criteria that matter
- European Central Bank testing: the model must appear on the ECB's public list of tested devices. This is the knockout criterion — without it, nothing else matters.
- Number of checks: the more simultaneous analyses (IR, UV, MG, thread, size, thickness, colour), the harder it is for a counterfeit to slip through. Professional-grade equipment works with 7.
- Speed and handling: half a second per note and acceptance in all 4 orientations keep the queue moving; the decision must be automatic, with no interpretation from the cashier.
- Currencies and updates: if you take pounds and euros — or any other mix — check which currencies the device supports and that it can be updated for new note series and currencies.
- Format: a compact counter-top unit for the till; if you take cash on deliveries, at markets or at events, look for battery compatibility.
Our recommendation by type of business
For the counter of a shop, pharmacy, convenience store or off-licence: a compact automatic detector with 7 checks such as the D7X, which verifies in 0.5 seconds, handles pounds and euros, and pays for itself with the first notes it rejects.
For taking cash on the move — deliveries, markets, fairs, taxis: the same D7X combined with the B1 rechargeable battery, which frees you from the plug socket.
Both models add up the value of what you verify and break it down by denomination; if you want that total on a colour screen — small cash-ups, shift changes: the D7T+ adds a TFT screen.
If your problem is volume — supermarket, petrol station, gaming venue: move up to a banknote counter with built-in detection, such as the V10 to V40 range, which verifies the notes while counting them at 1,000 per minute.
Warning signs when comparing
Be wary of equipment without verifiable ECB testing, of product pages that do not say how many checks the device performs or which currencies it supports, and of prices with no warranty or technical support behind them. A detector is security equipment: a €30 saving is paid back with the first fake note accepted.
Frequently asked questions
How much does a good counterfeit money detector cost?
A tested professional-grade automatic detector costs around €100 (approx. £85) — less than two fake £50 notes accepted. Manual formats (pen, UV lamp) are cheaper but require interpretation, offer no guaranteed detection — and the pen is meaningless on polymer notes.
Is it worth it for a small shop?
That is where it shows most: in a small shop, a single fake £20 or £50 can wipe out the day's margin. Automatic checking does not depend on the experience of whoever is on the till.
Stand-alone detector or banknote counter with detection?
If your bottleneck is verifying note by note at the till, a counter-top detector. If it is counting the cash at close of day, a banknote counter with detection: it verifies and counts in the same pass.
