Choose a banknote machine by the decisions it must make. Counting pieces, totaling mixed denominations, checking authenticity and sorting worn notes are different jobs. A fast machine is useful only when its outputs support the way your business records and handles cash.
Start with the currencies and note series you receive, typical batch sizes, staff time available and what happens to notes after processing. Requirements for notes recirculated through a cash dispenser can differ from those for a shop preparing a bank deposit.
Write the required functions separately
Scroll sideways for all columns. Keyboard users can focus the table and use the arrow keys.
| Task | Expected output | Question for a supplier |
|---|---|---|
| Piece counting | Number of notes in a batch. | Does the mode count pieces only, or recognize denomination? |
| Value counting | Count and value by supported denomination and currency. | Can currencies be mixed, or must they be selected and processed separately? |
| Authenticity checking | Classification based on the machine’s supported checks. | Which model, software, currency and test listing support the claim? |
| Fitness sorting | Separation by physical condition for the intended reuse. | Which sorting categories and output pockets are available? |
A simple piece counter can give a count without knowing the monetary value. A value counter needs a supported recognition mode. A machine advertising several currencies may require one currency per run. Verify these details in the exact model's operating instructions before planning a mixed-cash workflow.
Ask how rejected notes are separated and identified. An unreadable, folded, unsupported or suspect note may require different follow-up. Staff need the reason code and the approved handling procedure, not a habit of repeatedly feeding every rejected note until it is accepted.
Check evidence for the currency and intended use
For euro banknotes, the ECB's cash-handling framework covers authenticity, fitness and recirculation. Its cash-professional resources distinguish tested banknote-handling machines from authentication devices. Select the category that matches your task and follow the relevant national central bank's requirements.
For Bank of England notes, the Bank's machine-testing resource identifies models and software versions. It also explains that testing uses a sample model, and directs readers to the framework's limitations. Match the software or firmware installed on the machine you will actually use.
Record the manufacturer, exact model, software version, supported denominations, test-list date and applicable jurisdiction. A test result has a defined scope; a seller's general “approved” claim needs that detail. For another currency, use its issuing authority's guidance and the manufacturer's supported-currency documentation.
Measure a complete work cycle
Prepare a documented batch of known genuine notes appropriate to the machine and your procedures. Have two people independently verify the starting count and value. Use the manufacturer's prescribed settings. Record accepted notes, rejects, jams, manual handling time and the final reconciliation. Treat this as a usability and recordkeeping trial; it does not establish counterfeit-detection performance.
Fictional batch reconciliation
A trial begins with 40 notes of denomination 20, 30 of denomination 10 and 30 of denomination 5: 100 notes worth 1,250 currency units. The accepted output contains 39, 30 and 29 respectively: 98 notes worth 1,225. The two rejected notes, one 20 and one 5, account for the remaining 25.
The batch reconciles: 98 + 2 = 100 notes and 1,225 + 25 = 1,250 units. Keep the rejected notes distinct until their status is resolved under the applicable procedure. Counting them in the reconciliation does not classify them as authentic or fit.
If feeding takes one minute and preparation, reject review and recording take four more, the complete five-minute cycle handles 100 ÷ 5 = 20 notes per staff-minute. This fictional result shows why advertised feed speed and end-to-end labor productivity are different measures.
Download the machine trial and batch record. Use it to compare suppliers with the same notes and task, including interruptions and the time needed to explain a discrepancy.
Plan updates and exception handling
Before purchase, identify who provides software updates, how note-series changes are supported, whether servicing is local, and how operations continue during a failure. Ask for the cleaning and maintenance schedule in the manual and keep a dated service record. Test any export with your actual reconciliation process.
For unexplained differences, preserve the original count, machine totals and rejected-note record. Recount under your cash-control procedure and isolate the cause before combining the batch with another. Staff should know whom to contact about a suspected counterfeit and follow the issuer's or local authority's instructions; the applicable process varies by country.
Use financial data-quality checks to design the recordkeeping around the machine. Good reconciliation connects a physical batch to its record and leaves an understandable trail when an exception occurs.
