A barcode scanner is a device that reads barcode and QR code information and inputs it to a computer or other device. A handheld 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 to replace manual data entry to improve work efficiency. It is widely used in supermarkets, payments, logistics and express delivery, libraries, medical care, product traceability, asset management, government affairs processing, inventory and tallying, etc., to scan the barcodes of goods and documents to achieve information management and use. How many ways are there for our common handheld barcode scanners to upload scanned data to a computer?
Wired connection method of handheld barcode scanners:
Barcode scanners are connected via USB data cable: This is the most common connection method. Handheld barcode scanners are usually equipped with USB interfaces. Users only need to connect the scanner to the computer via a USB data cable, and the computer will automatically recognize the scanner and use it as an input device.
Serial port connection
Interface type: Some traditional handheld barcode scanners may use serial port connection, such as RS-232 interface, which is usually used in some specific industrial equipment environments.
Barcode scanner wireless connection method
Bluetooth wireless connection and pairing: With the development of wireless technology, Bluetooth connection has become a popular choice. Wireless barcode scanners are paired with computers or mobile devices via Bluetooth to ensure wireless transmission of wireless barcode scanner data. In open places, the Bluetooth transmission distance is 50-100 meters, and tablets and mobile phones can be connected. This method has high freedom, and users can operate in a larger range, which is suitable for warehouse management, retail cashier and other scenarios
Wi-Fi connection: Some high-end wireless barcode scanners support Wi-Fi connection, which can send data to computers via wireless network. This method is suitable for large enterprises that need real-time data synchronization and management. Users can collect data in a larger range without worrying about signal interference.
2.4 Link: The wireless barcode scanner can also be connected to a computer through 2.4G transmission distance of 50 meters in an open place. It is a transmission method of the wireless barcode scanner.
