QR code scanners are instruments for scanning QR codes. Common types include embedded, fixed, and handheld. QR codes have a wide range of application scenarios. With its large information capacity, high confidentiality, wide coding range, high decoding reliability, strong error correction ability, and low cost, it plays an important role in various fields. Whether a QR code scanners saves scanning records depends on its type, purpose, and specific settings. Our common QR code scanners generally confirm whether the scanner needs to be stored based on the usage scenario and function.
1. Hardware scanners Industrial scanners usually do not actively save records. Most basic scanners are only responsible for transmitting data to the connected computer or system in real time, and the device itself does not store records for a long time. In some offline scanning modes, some industrial scanners have storage functions. When there is no network connection, data can be temporarily stored and uploaded after the connection is restored.
2. Mobile scanning applications (such as WeChat, third-party apps), WeChat/Alipay and other built-in functions generally do not actively save scanning history, but some operations (such as payment codes) may generate transaction records.
3. Can the QR code scanners store data? Usually in some places with a relatively close range, such as in supermarkets and warehouses, the QR code scanners can directly transfer the real-time data of the scanned data to the computer via USB when it is working. In some environments where direct USB connection and transmission are not possible, we can transmit by connecting Bluetooth and wifi. In some special usage scenarios, when the QR code scanners cannot transmit data immediately, it can have its own storage function. The scanned information is stored on the scanner gun, and the data is uploaded to the computer when the connection is restored. Whether the QR scanner saves records depends on the design of the specific device and application. When we purchase and use it, we can clearly see the parameters of the QR code scanners for scanning and purchase it. If we order in large quantities, we can customize with the manufacturer whether the QR code scanners needs to have a built-in storage function according to the actual situation?
