Quick answer: CIS (Contact Image Sensor) is a line-scan image sensor inside a money counting machine. It captures an image of every banknote as it passes through, so the machine can recognise the denomination, add up the total value of a mixed stack, read serial numbers and judge note condition. A machine with Dual CIS scans both sides of each note; a Single CIS machine scans one side. CIS is not a counterfeit detector on its own; it works alongside UV, magnetic (MG), infrared (IR) and ultrasonic (US) sensors.
Finloyd has supplied money counting machines to banks, exchange houses and retailers in Saudi Arabia since 2008, from branches in Riyadh, Jeddah and Al Khobar. This guide explains what CIS actually does with Saudi riyal notes, when you need it, and which machine fits your cash volume.
What does CIS stand for?
CIS stands for Contact Image Sensor. It is a thin bar of tiny light sensors and LEDs, the same technology used in flatbed scanners, mounted across the note path. As each note moves past at up to 1,500 notes per minute, the sensor builds a full image of it line by line. The machine’s software then compares that image with the stored templates for each currency and denomination.
How does a CIS money counter work, step by step?
- Feeding: the hopper pulls notes one at a time into the transport path.
- Imaging: the CIS bar scans the note in colour (one side or both sides).
- Recognition: software matches the image to a denomination, for example 50 SAR or 500 SAR, and to its face and orientation.
- Authentication: UV, MG, MT, IR and US sensors check security features at the same moment.
- Decision: genuine notes go to the stacker; suspect, unknown or damaged notes stop the machine or drop into a reject pocket.
- Reporting: the screen shows the piece count, the total value and a breakdown per denomination, which can be printed or sent to a PC.
Why do Saudi riyal notes need an image sensor for mixed counting?
Saudi banknotes are too close in size for a basic counter to tell them apart. According to the Saudi Central Bank (SAMA), the sixth-issue notes range from 145 mm to 166 mm wide:
| Note | Size (mm) | Colour |
|---|---|---|
| 5 SAR (paper and polymer) | 145 × 66 | Purple |
| 10 SAR | 150 × 68 | Brown |
| 50 SAR | 155 × 70 | Green |
| 100 SAR | 160 × 72 | Red |
| 200 SAR (issued 2021) | 163 × 73 | Grey |
| 500 SAR | 166 × 74 | Blue |
The 100, 200 and 500 SAR notes differ by only 3 mm each. A worn or slightly skewed note can blur that difference, so reliable mixed (total value) counting depends on reading the note’s image, colour and print, which is exactly what CIS does. The polymer 5 SAR note adds a transparent window, so make sure any machine you buy has firmware that recognises it.
Single CIS vs Dual CIS: what is the difference?
| Single CIS | Dual CIS | |
|---|---|---|
| Sides scanned | One side | Both sides in one pass |
| Mixed value counting | Yes | Yes, more robust with worn notes |
| Face and orientation sorting | Limited | Yes |
| Fitness sorting (ATM-grade notes) | No | Yes, on fitness models |
| Typical users | Shops, cashiers, small cash offices | Banks, exchange houses, cash centres, CIT |
| Finloyd examples | Kisan K2 | CX-7500, Fin-7900, Newton 3F, K3-A, K5-A, K6 |
CIS vs UV, MG, MT, IR and US: what does each sensor check?
| Sensor | Full name | What it checks | Main job |
|---|---|---|---|
| CIS | Contact Image Sensor | Full-colour image of the note | Denomination, value counting, serial numbers, fitness |
| UV | Ultraviolet | Fluorescent features and paper brightness | Counterfeit detection |
| MG | Magnetic | Magnetic ink pattern (more channels = finer reading, e.g. 18-channel) | Counterfeit detection |
| MT | Metal thread | Embedded security thread | Counterfeit detection |
| IR | Infrared | Infrared-visible ink areas | Counterfeit detection |
| US | Ultrasonic | Note thickness | Double notes, tape and repaired notes |
Does CIS detect counterfeit money?
Not on its own. CIS recognises what a note looks like; counterfeit detection comes from UV, MG, MT and IR checks running at the same time. A good counterfeit can look right to an image sensor and still fail the magnetic or infrared test. That is why every Finloyd value counter combines CIS with at least UV, MG and IR. For spot checks at a till, a desktop fake note detector is a low-cost add-on.
Can a CIS machine read serial numbers?
Yes, when the model has serial number OCR. The CIS image is passed to OCR software that records each note’s serial number. In Finloyd’s range, the K2, Fin-7900, Newton 3F, K3-A, K5-A and K6 support serial number reading; the CX-7500 does not.

Counting coins as well? The Fin-CC93 coin counter handles riyal and halala coins.
Do you actually need a CIS machine?
- You count bundles that are already sorted by denomination: a sheet counter such as the Fin-890 or Fin-3100 is enough and costs less.
- Your tills hold mixed 5 to 500 SAR notes and you need the riyal total: choose a CIS value counter such as the CX-7500 or K2.
- You handle several currencies (exchange house, hotel, airport): Newton-A or Fin-7900.
- You load ATMs or deposit to banks: a Dual CIS fitness sorter such as the Newton 3F, K3-A or K5-A.
- You process very large daily volumes: the K6 sorting and strapping system.
5 questions to ask before buying a CIS money counter in Saudi Arabia
- Does it value-count all current riyal notes, including the 200 SAR and polymer 5 SAR?
- Is it Single or Dual CIS, and do I need face, orientation or fitness sorting?
- Which counterfeit sensors run alongside CIS: UV, MG, MT, IR, US?
- Can the supplier update firmware locally when SAMA issues a new note?
- Who services it in my city, and how fast? Finloyd provides door-to-door maintenance in Riyadh, Jeddah and Al Khobar.
Frequently asked questions
What does CIS mean in a money counting machine?
CIS means Contact Image Sensor. It scans an image of each banknote so the machine can identify the denomination, count the total value of mixed notes, read serial numbers and check note condition.
What is the difference between Single CIS and Dual CIS?
Single CIS scans one side of each note; Dual CIS scans both sides in one pass. Dual CIS is needed for face and orientation sorting and fitness sorting, and is more reliable with worn notes.
Does a CIS sensor detect fake notes?
No, not by itself. CIS recognises the note; counterfeit detection comes from UV, magnetic, metal-thread and infrared sensors working with it.
Can a normal money counter count mixed Saudi riyals?
A basic sheet counter counts pieces only. To get the riyal total of a mixed stack you need a value counter with an image sensor, because 100, 200 and 500 SAR notes differ by only 3 mm in width.
Does the machine need an update for the polymer 5 riyal note?
It needs firmware that includes the polymer 5 SAR template. Ask your supplier to confirm before purchase; Finloyd updates supported models locally.
Which Finloyd machine is best for a supermarket or retail shop?
For mixed tills, the CX-7500 (Dual CIS) or Kisan K2 (Single CIS with a reject pocket). For pre-sorted bundles, the Fin-890 or Fin-3100.
Where can I buy a CIS money counting machine in Saudi Arabia?
Finloyd supplies, installs and services CIS money counters from its branches in Riyadh, Jeddah and Al Khobar, with delivery across the Kingdom.
