A barcode scanner is a device that reads barcodes and QR code information and inputs it to computers and other devices. The barcode scanner uses optical principles to illuminate the barcode symbol through a light source, decodes the barcode content, and transmits the data through a data line or wirelessly. In actual applications, almost all data is transmitted to the background server. The purpose is to replace manual data entry to improve work efficiency. How many types of barcode scanner are there? Barcode scanner can be divided into many types according to different classification standards. The following are common classifications and their characteristics.
Classification by scanning technology:
Laser scanner: Scans barcodes by emitting laser lines through laser diodes. It is suitable for scanning one-dimensional barcode Scanner. The scanning distance is long (up to several meters). It cannot read screen barcodes or damaged barcodes. It is suitable for traditional barcode environments such as warehouses and retail stores.
CCD scanner (red light scanner): Uses LED red light to illuminate barcode Scanner and captures reflected light through sensors. It is durable and low-priced, but cannot scan long-distance or high-density barcodes. It is suitable for daily scenes such as convenience stores and small stores.
Image scanner (2D scanner): uses a camera to shoot barcodes, decodes through image processing technology, supports one-dimensional codes, two-dimensional codes (such as QR codes) and screen barcodes, and can read damaged, blurred or bent barcodes. Applicable to: mobile payment, logistics, medical and other scenarios that require high compatibility.
Classification by interface type:
Wired scanner: USB (plug and play), PS/2 (keyboard interface required), stable power supply, no delay, suitable for fixed workstations.
Wireless scanner: connected via Bluetooth, Wi-Fi, radio frequency (RF), flexible and mobile, wide coverage (up to 100 meters)
Classification by appearance:
Handheld scanner: the most common, requires manual alignment of barcodes, flexible and portable.
Fixed scanner: installed on a bracket, automatic induction scanning (such as supermarket checkout counter).
Wearable scanner: ring type or glove type, freeing your hands.
Classification by usage scenario:
Commercial-grade scanner: lightweight, cost-effective, suitable for medium and low-intensity environments.
Industrial-grade scanners: manufacturing, outdoor logistics, and port transportation.
Barcode scanners, wireless collectors, logistics express cabinets, e-commerce self-pickup cabinets, smart home lockers, ATM self-service cabinets, self-service inquiry terminals, queuing equipment, lottery machines, document manufacturing equipment, etc.
