During the process of industrial production, handheld terminal RFID mobile phones are often used. However, according to the different implementation methods of the data collector, its types and applications are also diverse. Especially RFID mobile phone, it has realized the mobile function of the radio frequency identification technology, and its small module includes the identification power of multiple frequency bands. When we choose rugged handhelds, we often hear data collection methods such as RFID and NFC. However, what is the difference?
In the application. In fact, RFID and NFC have many similarities. In addition to the application environment and frequency bands used, they also have many industry standards. Radiofrequency identification is an automatic identification technology that uses radio waves to communicate. The basic principle is to carry out data communication through electromagnetic coupling or inductive coupling between the reader and the tag attached to the object, so as to realize the automatic identification of the tag object. NFC is short-range wireless communication technology.
Many people's perceptual understanding of RFID comes from an IBM advertisement: A young man shopping in a supermarket stuffs goods in his trench coat when shopping, and receives the bill directly after arriving at the checkout without spending money. This advertisement shows the application of RFID technology in daily life.
Radiofrequency identification is an automatic identification technology that uses radio waves to communicate. The basic principle is to carry out data communication through electromagnetic or induction between the reader and the tag attached to the object, so as to realize the automatic identification of the tag object. Automatic recognition refers to the use of certain recognition devices to automatically obtain relevant information of the recognized object through the proximity activity between the recognized object and the recognition device, and provide it to a durable computer processing system to complete related subsequent processing.
NFC is also short-range wireless communication technology. It can perform short-range wireless communication between mobile devices, consumer electronics, personal computers, rugged tablet computer and smart control tools. NFC provides a simple touch solution that allows consumers to exchange information, access content and services simply and intuitively. NFC is developed based on RFID. NFC is essentially not much different from RFID, and both are based on signal transmission between two objects with similar physical locations.

The Beidou handheld terminal is a handheld terminal with Beidou functional modules. The function of the Beidou handheld terminal is to obtain faster and more accurate location information services in navigation applications. It can be widely used in scenarios that cannot be covered by conventional communication networks, such as offshore fishery, emergency rescue, and forest fire prevention. A professional rugged computer manufacturer like Emdoor is dedicated to provide customer the high quality rugged handheld pc.
1. Logistics: typically for tobacco distribution, warehouse inventory, postal distribution, terminal distribution of major daily necessities manufacturers, drug distribution, large factory logistics, warehouse transportation.
2. Warehouse management: chain stores/shops/counters, collecting and transmitting store purchase and sales, inventory adjustment, unsubscribing, membership management and other data. Shoes and apparel orders will be used in wireless order meetings in the shoe and apparel industry to scan barcode orders through rugged handheld.
3. Forestry inspection: Through the positioning function of the Beidou handheld terminal, the dynamics of the rangers can be caught in time by people in other systems at any time, and once an accident occurs in the mountain forest, it is also convenient for others to save themselves. It greatly protects the personal safety of the forest rangers.
