Star Micronics 37950920 Handheld 2D Barcode Scanner
Overview
The Star Micronics 37950920 (BSH-20U) is a compact handheld scanner built around a 2D image sensor capable of reading both 1D linear codes and 2D matrix codes in a single pass. Unlike laser-based scanners, the imaging approach means the 37950920 handles damaged, poorly printed, or curved barcodes more reliably — a real advantage in retail and warehouse environments where label quality varies. Wired USB connectivity eliminates battery management and wireless pairing complexity; the scanner is ready to work the moment you plug it in.
Key Features
- 2D Image Sensor (1D/2D Barcode Capability): Reads UPC, Code 128, QR codes, Data Matrix, and PDF417 in a single capture event. No switching modes or multiple scans — reduces transaction time and operator frustration at checkout or during receiving operations.
- Wired USB Connectivity: Draws power and communicates over a single USB cable. No wireless dropout risk, no batteries to charge or replace between shifts, and no licensing fees for proprietary wireless protocols. Ideal for fixed workstations where the scanner stays tethered to the POS terminal.
- Single-Pass Scan: Captures 1D and 2D codes with one trigger pull. Operators don't need to know what barcode format they're scanning — the device handles it automatically, speeding up checkout lines and reducing training burden.
- Black Finish: Neutral appearance blends into any POS counter or warehouse terminal setup without aesthetic friction.
- Standard POS Integration: Operates as a USB HID (Human Interface Device), presenting barcode data as keyboard input. No custom drivers or middleware required for most POS systems, making deployment straightforward across retailers, logistics hubs, and hospitality venues.
Integration & Compatibility
The 37950920 integrates directly into any POS application or warehouse management system that accepts USB keyboard input. It requires no special software or network configuration — just plug, authorize the barcode format settings if needed, and scan. Works with Micros, Square, Toast, custom legacy POS systems, and mobile checkout carts as long as they have a USB port. In warehouse environments, pairs seamlessly with WMS systems that log inventory via barcode input.
The wired design makes it a better fit for stationary checkout counters and warehouse receiving docks than for mobile picking operations — consider a wireless or Bluetooth variant from the Star Micronics scanner line if your team needs to roam beyond a cable's length.
When to Choose a Different Model
If your operation requires mobility beyond 10–15 feet of a terminal, or if your warehouse uses mobile picking carts with no fixed USB anchor point, evaluate a wireless or Bluetooth scanner in the Star Micronics family instead. If you need to capture 2D codes at very high speed (high-volume parcel sorting), confirm the 37950920's frame rate meets your throughput targets — the datasheet will specify maximum scans per second under real-world lighting. For specialty applications (ultra-rugged drop testing, extreme temperature exposure, or hazardous locations), consult the full technical specifications or the manufacturer directly.
Frequently Asked Questions
Q: Does the Star Micronics 37950920 work with my existing POS system?
A: If your POS accepts USB keyboard input, yes. The 37950920 presents barcode data as standard keyboard characters, requiring no custom integration or drivers. Check your POS vendor's documentation or contact them with the model number to confirm compatibility.
Q: Can the 37950920 read damaged or faded barcodes?
A: The 2D image sensor is more tolerant of print quality issues than laser scanners, but severely faded or obscured codes may still fail. Test with samples of your actual barcode labels before purchase.
Q: What is the range at which the 37950920 can read a barcode?
A: Typical handheld 2D scanners work effectively from 2–12 inches away, depending on code size and lighting. Consult the datasheet for the exact working distance specification for the 37950920.
Q: Is the 37950920 cable replaceable if it gets damaged?
A: Most handheld scanners use standard USB cabling. Confirm with the manufacturer or reseller whether the cable is field-serviceable before purchase.
Q: Can I use the 37950920 with a USB extension cable?
A: Yes, but use a powered USB hub or high-quality shielded extension (no longer than 10 meters) to avoid signal degradation or power drop. Test with your specific POS setup.

The Star Micronics 37950920 is a straightforward wired 2D imaging scanner — no wireless overhead, no battery logistics, just plug and scan. The 2D sensor is the real story here: unlike older laser scanners, the 37950920 reads 1D and 2D codes in a single pass without mode switching, which cuts transaction time and training burden in retail and warehouse settings.
Technical Highlights:
- 2D Image Sensor (1D/2D): Single-pass reading of UPC, Code 128, QR, Data Matrix, and PDF417 eliminates the need for operator knowledge of barcode formats — everyone scans the same way, reducing checkout friction and mistakes.
- Wired USB: No batteries, no Bluetooth pairing delays, no wireless license costs. The 37950920 is always powered and always connected to the terminal. In retail, this means zero mid-shift downtime from dead batteries or lost signal.
- USB HID Protocol: Presents barcode data as keyboard input, so integration is minimal — POS systems that accept typed input (nearly all do) will work with the 37950920 out of the box. No driver installation or middleware overhead.
Deployment Considerations:
- The 37950920 is tethered by its USB cable. It's perfect for checkout counters and warehouse receiving stations, but not for mobile picking or cross-dock operations where range and portability matter.
- 2D imaging is more forgiving than laser scanning when barcode labels are creased, partially obscured, or printed on curved surfaces — common in warehouse and logistics environments. Test with your actual label stock before full rollout.
Deploy the 37950920 where your scanners stay rooted to a workstation: retail checkouts, warehouse in-bounds, customer service counters. If your team is mobile, or if you need scanning from 20+ feet away, look for a wireless variant in the Star Micronics catalog.
