A wireless barcode scanner is an indispensable assistant for quick identification of goods. The compact device allows you to read marking information while moving around the room with products, which makes working with it efficient, simple and comfortable. Anyone who has chosen a model for their needs in the catalog can appreciate the advantages of wireless scanners https://yutis.com.ua/skanery-shtrih-koda/besprovodnye-skanery-shtrih-kodov. But in order to buy exactly the right device, it will not be superfluous to understand their features and types.
How does a wireless scanner work?
The principle of operation of the wireless device is relatively simple: the device reads the barcode from the product and transmits the information in real time to a computer, cash register or other external equipment. Decrypted data is transmitted via wireless technologies - Bluetooth or Wi-Fi. The built-in battery is responsible for powering the device.
Scanners have built-in memory. Therefore, if the employee leaves the scanning area during the reading process, the information is still saved. When the signal is restored, the device transmits data to external equipment.
What are the types of wireless scanners?
One of the main criteria for the classification of scanners is the method of reading the barcode. According to this parameter, three types of devices are distinguished:
- LEDs - recognize the marking under the influence of the LED: the beam hits the bar code, is reflected, returns back and hits the CCD matrix. Such devices have a short reading range, so they must be brought close to the barcode. The advantage of LED models is the combination of an affordable price and stable operation.
- Laser - read information due to the reflection of a laser beam. The main advantage of scanners is that they recognize barcodes from a long distance, so when using the device there is no need to bring it close to the product.
- Imagers are scanners that photograph the code and store the image in memory. They can read information at different angles and at considerable distances. Imagers recognize unclear and damaged markings.
Wireless devices are also distinguished by the type of readable data. There are two types of scanners:
- for linear or one-dimensional markings;
- for two-dimensional markings.
Devices that can decode two-dimensional codes can also read linear markings. But not vice versa - scanners for one-dimensional markings do not recognize two-dimensional barcodes.
How to choose a barcode scanner?
Modern manufacturers offer many wireless scanners of different models - how not to get confused in the variety and buy the best option for your working conditions? A few additional selection criteria will come in handy here. In addition to the peculiarities of reading information, consider the following nuances:
- The connection interface is Bluetooth or Wi-Fi. Their main difference is the range: a device with a Bluetooth connection allows an employee to read data within a radius of 10-15 m from the signal source, and with a Wi-Fi connection - within a radius of 100 m. Therefore, when buying, you need to take into account the area of the store, warehouse or other the premises in which the wireless device is planned to be used.
- The speed of reading is indicated in the number of scans in 1 second. It directly affects the operability of working with the scanner.
- Battery capacity – the higher the value, the more reading can be done in offline mode until the next recharge.
- Degree of protection - models may differ in levels of strength and moisture resistance. When choosing, be guided by the conditions of use of the device.
