The bar code scanning gun market cannot be replaced by mobile phones.

Release Time:2017-08-17

Some customers have asked me that mobile phones can also scan codes, and barcode scanning guns can also scan codes. What is the difference between them? Since everyone has mobile phones, why should they spend money to buy code scanning guns. The bar code scanning gun market cannot be replaced by mobile phones. Today, I will analyze it with you: What is the difference between professional bar code scanning guns and mobile phones?

1. from the professional product performance analysis:

The difference in design

The barcode scanning gun has a dedicated barcode scanning engine, which is used to scan and analyze the barcode two-dimensional code.

The mobile phone scans the two-dimensional code by relying on the camera to capture the picture, and the built-in software analyzes and outputs it twice. At the same time, the mobile phone is a multi-functional application, and scanning code is only one of them.

The difference in decoding

Professional barcode scanning guns belong to "hard decoding" and have dedicated decoding chips and cameras in them. The decoding speed is calculated at the millisecond level.

Mobile phone scanning two-dimensional code is a built-in decoding software that decodes and outputs the photos taken. The success rate of decoding and the type of barcode supported depend entirely on the calculation method of decoding software and how to allocate mobile phone hardware. The time taken in this process is definitely much longer than that of professional barcode scanning equipment. Mobile phone scanning barcode two-dimensional code is commonly known as "soft decoding".

2. analysis from the use of professional products:

The difference in mode of operation

The aiming mode of the barcode scanning gun is called external aiming. When the key switch is activated, there will be an aiming line (frame, center point, etc.) to help you align the barcode.

The mobile phone has to put the bar code on the screen, which is very slow and inconvenient to operate, and the work efficiency is greatly reduced.

Communication protocol difference

The scanning gun basically supports USB port, RS232 serial port and network port communication. Basically, all application software using the scanning gun uses these communication protocols, and the decoding results are directly output to the application software. Such as supermarket cash register, manufacturer traceability system, logistics storage system, warehousing system, etc.

The results of mobile phone scanning are only displayed on the screen of your mobile phone, or you can only communicate and interact with the APP on your mobile phone. If you want to communicate with PC or other devices, the workload in the middle is too large and thankless.

After reading the above analysis, can you understand that there is a specialization in the technical industry, and when a function is brought into full play, it is also an excellent product. Yongli scanning gun brand 1920 can read the screen one-dimensional two-dimensional code payment image type two-dimensional scanning gun, support RS-232, USB, PS2, virtual USB and other PC interfaces, can read Chinese characters. Strong and durable, has a good price, very suitable for supermarkets, shopping malls, tobacco monopoly, medicine and warehouse environment.
