[Epidemic News] 3 Quick Scans for Vaccine Passports! A must for restaurants and merchants!
The epidemic has eased and the anti-epidemic policies have gradually been relaxed. However, if citizens want to dine in restaurants, they need to scan the needle card or recovery pass first. However, many merchants and restaurants have reported that when they want to scan the QR code To scan failure, or failed to read data and other issues. This time, I will wait for the editor to teach the managers of restaurants and merchants some scanning experience, so that the scanning time can be shortened, and customers can be rotated naturally.
1. The light source should be sufficient
Many merchants use government software on their mobile phones to scan the QR code data with the camera of the mobile phone. However, if the reading environment is not bright enough, the camera lens of the mobile phone may not be able to capture the image of the QR code smoothly, so try to place the relevant devices in the A location where a light bulb or light tube is illuminated to ensure that the QR code can be projected into the lens of the device.
2. Use a device specially designed to read QR codes
At present, most mobile phones are used as devices for reading QR codes. However, due to the specifications of mobile phones, they are not originally designed for reading QR codes. Therefore, when scanning relevant information, they are usually used exclusively for reading QR codes. The device takes more time. If the merchant wants to quickly read the needle card or recovery pass, there are now some vaccine scanning device options, and LINKO Shop also has related products for purchase.
3. It is better to use the rear lens than the front lens
Generally, merchants set up a front camera as the main lens for reading QR codes in order to make it convenient for customers to display QR codes. However, since the pixels of the front camera of a mobile phone are usually worse than those of the rear camera, the reading effect will be relatively poor. Poor, it will take a long time to successfully read the data, so if you are using a mobile phone, please use the rear camera of the mobile phone as much as possible, or directly purchase a device that can be directly used to scan the QR code.
