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.The main differences between a wired barcode read and a wireless barcode scanner are reflected in connection methods, usage scenarios, function expansion and cost.
Connection method:
Wired barcode scanners are mainly connected through physical cables, and are connected to computers or terminal devices through USB, PS/2 and other interfaces. No additional configuration is required, plug and play, strong compatibility, fast transmission speed, and no need to consider battery life.
Wireless barcode scanners transmit data through Bluetooth, WI-FI or 2.4Ghz wireless, are not bound by cables, and are suitable for large-scale mobile activities. They are suitable for warehouses, logistics, and outdoor use. Receivers need to be configured and batteries need to be charged or replaced regularly.
Usage scenarios:
Wired barcode scanners are generally used in fixed places, such as cash registers, fixed workstations, small stores, and other scenes that do not require frequent movement. They are suitable for places with high real-time requirements and avoid signal interference.
Wireless barcode scanners are used in mobile scenarios, warehousing and logistics, large shopping malls, supermarkets, mobile cashiers, and outdoor operations that require flexible operation. They support 10-100 meters of transmission and are suitable for cross-regional use.
Functions and performance:
The data of wired barcode scanners is transmitted instantly without delay, powered by the computer host, and no additional charging is required.
The wireless barcode scanner is lightweight and suitable for carrying or holding. Some high-end models support data caching. When the network is disconnected, data can be temporarily stored and synchronized after networking, but battery life needs to be concerned.
Cost and maintenance:
The price of wired barcode scanners is relatively low, and there is no battery loss problem, but the cable is easy to wear and needs to be replaced regularly.
The wireless barcode scanner needs to manage battery life and charging equipment, and needs to replace batteries or receivers.
When we choose a barcode scanner, we need to choose a barcode scanner with different performance according to different usage scenarios. NUTEM is a factory specializing in barcode scanners with 15 years of experience and can OEM/ODM.
