RFID (Radio Frequency Identification) technology is a non-contact automatic identification technology that has been widely used in various industries in recent years. Enterprises have an increasing demand for mobile data collection with information technology. Handheld RFID card readers have become popular devices for rapid data collection in various industries. Due to differences in electronic tags, radio frequency bands, and application scenarios, the modes of the handheld rfid tag reader are also very different. Many users are confused when they choose for the first time. They often don't know what frequency band to choose (low frequency, high frequency, ultra-high frequency), which equipment is more suitable for their project needs, and which durable product. Next, DTB RIFD will introduce the selection criteria of handheld RFID tag readers.
1. RF requirements, business requirements, and application scenarios
From the perspective of power supply status, RFID tags are divided into two categories: active and passive. From the standpoint of operating frequency, it can be divided into several categories, such as low frequency (LF), high frequency (HF), and ultra-high frequency (UHF). Each frequency has its characteristics and is used in different fields. For example, high frequency rfid tags are used in public transportation. Therefore, when users choose a handheld RFID tag reader, they should first consider their radio frequency requirements, their business requirements, and application scenarios.
You should consider the hardware price of handheld RFID tag readers and the cost of development tools, hidden fees in the development of application software, and maintenance costs after the product is put into use.
3. Memory capacity
The memory capacity of the handheld RFID tag reader determines the data capacity, and its memory capacity corresponds to the processing speed of the CPU. If a low-performance CPU is used, blindly increasing its memory capacity will increase users' processing and waiting time.
