Analysis of Types and Application Fields of Commercial RFID Reader

Handheld pda devices are movable and portable electronic products. With the widespread application of RFID technology in industrial manufacturing, financial retail, public transportation, security and other fields, current pda devices are basically equipped with RFID modules, which can realize RFID electronic Reading of tags. What are the specific combinations of handheld pda devices and RFID technology? Let’s find out together.
 

There are many applications for commercial PDAs, including POS machines, handheld ticket machines, smart phones, etc. The second-generation certificates, membership cards, stored-value cards, access control cards, IC cards, etc. we use now are all designed based on RFID technology.
 

The second-generation ID card is uniformly issued by the state. The card is equipped with efficient password protection and cannot be copied or tampered with. However, the information on the ID card can be read through an RFID reader. The PDA used by conductors on the train to check tickets is equipped with an RFID reading and writing module. The handheld ticket inspection machine can not only read our identity information, but can also be connected to the ticketing system to check the arrival station and perform ticket replenishment and other operations. The consumption of radio frequency cards such as membership cards and stored value cards needs to be operated through POS machines with RFID modules.
 

Nowadays, many mobile phones are also equipped with RFID modules, such as electronic bus cards, which not only saves the cost of purchasing cards, but also avoids security risks caused by ordinary ID and IC cards being easily copied. In fact, every access control card also uses RFID, which contains personal information. When the access card comes into contact with the sensor, the sensor transmits the access card information to the system for matching. When the information is sensed, the door will be opened.
 

With the widespread application of RFID technology in various fields, pda equipment and RFID technology have gradually integrated, further expanding the application scope of RFID. When RFID technology is fully popularized, more and more devices will be organically integrated with RFID, creating a truly IoT world where everything can be connected.
