Adding a barcode scanner to a cash register speeds up transaction processing, eliminates manual PLU lookup errors, and scales with your inventory. It requires a register with a serial port. The Nadex CR360 and CR600 both support scanner, scale, and kitchen printer connections via serial port. The Nadex handheld barcode laser scanner ($67.99) connects directly to both models and is ready to use from day one. |
Why businesses add a barcode scanner to their cash register
A cash register without a barcode scanner requires the cashier to enter a PLU code manually for every transaction find the price, type the code, confirm the entry. In low-volume environments this is manageable. In environments with large inventories or fast-moving transaction lines, it becomes the bottleneck.
A barcode scanner eliminates that step. The cashier scans the product, the register retrieves the PLU and price automatically, and the transaction logs in real time. The U.S. Small Business Administration's guidance on managing your business notes that cash operations need to be structured around efficiency, and scan-speed at checkout is one of the most direct efficiency gains available without a software subscription.
The same principle applies to scales. If your business sells by weight deli counters, bulk food, produce, fabric by the yard a scale connected to the register calculates the transaction total automatically from the PLU weight rate without manual calculation.
How barcode scanning works with a cash register
A barcode scanner connected to an ECR works through PLU lookup. Every item you want to sell by scan needs a PLU assigned in the register with a barcode attached. When the cashier scans the barcode, the register matches it to the corresponding PLU and logs the price and department automatically.
Two things need to happen before scanning at your counter works.
First, program your PLUs with barcode numbers. Assign each PLU its barcode number the UPC or EAN on the product through the PC programming interface. This is done once per product and does not need to be repeated unless the price or department changes.
Second, connect a compatible scanner via serial port. The barcode scanner connects to the register through its serial port using a standard COM SERIAL connection. Once plugged in, the register recognizes scan input the same way it recognizes keypad input no software driver installation required.
The Nadex CR360 cash register includes a serial port for barcode scanner, kitchen printer, scale, and PC programming. The Nadex handheld barcode laser scanner is designed to work with it at $67.99 no additional configuration required.
Which Nadex registers support a barcode scanner?
The Nadex CR360 at $389.99 includes one serial port supporting connection to a barcode scanner, kitchen printer, scale, or PC programming interface one peripheral at a time. If you need a scanner and a kitchen printer connected simultaneously, the CR600 is the right model.
The Nadex CR600 at $599.99 includes two serial ports, supporting simultaneous connection of a barcode scanner and a second peripheral typically a kitchen printer or scale. This matters for food service operations that need both a customer-facing scanner at the counter and a kitchen printer routing orders to the back. The CR600 also adds a 7.5-inch operator display and 20 payment methods.
For businesses that only need a scanner at one station, the CR360 is the right starting point. For operations that need scanner and kitchen printer running at the same time, step to the CR600.
The Nadex handheld laser scanner: what you get
The Nadex handheld barcode laser scanner is purpose-built for the CR360 and CR600. At $67.99, it is the most direct path to a scanner-equipped counter without compatibility risk.
Type: Handheld laser scanner. Connection: COM SERIAL. Compatible models: Nadex CR360, Nadex CR600. Price: $67.99.
The scanner connects via the register's serial port and reads standard 1D barcodes found on retail products. Once connected and PLUs are programmed with their barcode numbers, checkout by scan works immediately no additional software, no network requirement, no subscription.
How a scale connects to a cash register
A scale sends the measured weight to the register through the serial port, which the register uses to calculate the line item total based on the PLU's price-per-unit setting.
-
Program the weight-priced item as a PLU with a price-per-unit (e.g., $4.99 per pound).
-
Place the item on the scale.
-
The scale sends the weight reading to the register via serial connection.
-
The register multiplies weight by price-per-unit and logs the transaction value automatically.
This removes manual weight entry and manual multiplication both sources of pricing error at a busy counter. The CR360 supports scale connection through its serial port. The CR600 supports scale connection on either of its two serial ports, leaving the second port free for a scanner or kitchen printer.
Adding a kitchen printer to the setup
A kitchen printer connected via serial port routes orders entered at the register directly to a printed ticket at the kitchen station, eliminating the handwritten ticket step.
Because the CR360 has one serial port, connecting a kitchen printer means that port cannot simultaneously run a barcode scanner or scale. For operations that need scanner-at-counter and kitchen printing simultaneously, the CR600 is the required model. The CR600's two serial ports handle both at the same time: port one for a scanner at the counter, port two for a kitchen printer at the prep station.
Pairing your register with a bill counter at close
A cash register records every transaction it does not verify the cash it receives. The Federal Reserve Currency FAQ confirms that detection pens are not always reliable against sophisticated counterfeits. The U.S. Secret Service counterfeit investigations division confirms that retail operations are a primary target for counterfeit currency distribution.
Pairing the register with a Nadex V1800 bill counter covers the cash verification side of the close workflow: fast, accurate checkout through a scanner-equipped register and verified cash at close through a bill counter.

Frequently asked questions
1. Does every cash register support a barcode scanner?
No. A barcode scanner requires a serial port on the register. All three Nadex models include serial port connectivity. Before purchasing any register for a scanning-enabled counter, confirm the port type and scanner connector compatibility.
2. Can I add a barcode scanner to my existing Nadex CR360?
Yes. The CR360's serial port supports barcode scanner connection. The Nadex handheld barcode laser scanner ($67.99) is purpose-built for the CR360 and CR600, connects via COM SERIAL, and is ready to use once PLUs are programmed with their barcode numbers.
3. What is the difference between one serial port and two?
A single serial port allows one peripheral at a time scanner, kitchen printer, or scale, but not two simultaneously. Two serial ports (CR600) allow two peripherals running at the same time. For a food service operation that needs both a scanner and a kitchen printer, the CR600 is the required configuration.
4. Can the cash register work with any barcode scanner?
For full compatibility, the scanner must use a COM SERIAL connection. The Nadex handheld barcode laser scanner is designed specifically for the CR360 and CR600 and confirmed compatible. Generic scanners may require additional configuration.
5. What happens if I need scanner, scale, and kitchen printer at the same time?
The CR600's two serial ports handle two simultaneous peripheral connections. For a three-peripheral setup, a serial hub or a more advanced POS system would be required. Most counter environments are adequately served by the two-port CR600 configuration.
