UHF RFID reader terminals come in various forms. Depending on the application scenarios, the final terminal forms are different. In the industry, readers are generally classified based on whether they are in a fixed position or can be moved when used. They are divided into two categories: Fixed readers and Mobile readers.

In this survey, based on market popularity, we selected large-volume and relatively high-priced products such as printers, smart cabinets, and channel reader from fixed readers for separate analysis.

The specific categories are:

• Handheld devices (Including other portable reader/writer devices). Among this type of products, the most important form is handheld devices. In addition, there are also some tablets and wearable products.  When applied to the market, they are all classified into the same category.

• Printer is a common form of RFID fixed reader and writer. It is mostly used for printing white label cards. Or the application terminal performs a small amount of re-labeling due to label loss.

Or scenarios such as logistics, finance, electricity, and medical care where the number of tags is relatively small and the degree of customization is high.

• Channel reader is a form of fixed reader that uses bayonet ports for warehouse entry and exit management and asset management.

• Discrete device readers and writers refer to UHF RFID readers and writers built with discrete devices.   They do not use standard chips. In some scenarios, such products can customized according to user needs.
