1. Look at the hardware: hardware determines most of the performance of the device. The performance, stability and cost performance of the product are basically determined by the choice of a good chip scheme by the manufacturer.
2. Look at the scanning module: select the scanning head according to its own application and barcode printing clarity, and select the scanning head that can meet the use requirements.
3. Look at the screen: Higher resolution can better support the software, display the operation interface in a good state, and improve the user experience. Proper brightness and contrast can also protect the operator's vision.
4. Look at the brand and scheme of WIFI: The brand and scheme of WIFI determine whether WIFI is stable and whether data transmission is fast. After you get the prototype, you can actually test it to see if there will be problems when WIFI runs for a long time, whether the data transmission is smooth, and whether WIFI will be disconnected frequently.
5. Look at the endurance: The endurance of the handset depends on the battery capacity and the power consumption of the whole machine. The larger the battery capacity, the lower the power consumption of the whole machine and the longer the service time. For the working time of the receiver, you can understand it by reading its manual, or you can actually test it with a prototype.
