Handheld rfid computer's advantages

As an indispensable part of the application system, the correct type selection of RFID reader will be related to the smooth implementation and implementation cost of the customer's project; In terms of reader selection, it is best to go through a strict process to ensure the success of the project.

First of all, it is necessary to pay attention to the frequency range of reader / writer equipment to see whether it meets the frequency specification of the project site;

Second, understand the maximum transmission power of the reader and whether the radiation of the supporting antenna exceeds the standard;

Third, look at the number of antenna ports provided by the reader and writer, and determine whether the application needs a multi interface reader and writer;

Fourth, whether the communication interface meets the needs of the project;

Fifth, understand the reading distance and anti-collision index. The reading distance index should specify what antenna and label are tested; Anti collision should be clear about what labels are arranged in what way and how long it will take to read them all;

Sixth, an RFID application system is not only related to the reader, but also related to the label, antenna, material of labeled items, movement speed of labeled items, surrounding environment, etc. before determining the equipment, it is best to simulate the on-site situation for testing and verification to ensure that the product can really meet the application requirements;

Seventh, continuously test the stability of the equipment under simulated conditions to ensure long-term stable operation.

Eighth, check whether the development materials meet the system development requirements. It's best to support the system you use, and it's best to have relevant routines. If not, the development time will be very long, or even the development can't go on.

Android uhf rfid reader's frequency 

RFID readers and writers can be divided into 125k, 13.56M, 900m, 2.4G and other frequency bands according to the frequency.

125k: generally called LF, it is generally used for animal husbandry management

13.56M: generally called HF, it is used for personnel management such as driving school communication and attendance. It can also be used for asset anti-counterfeiting management

900m: generally called UHF, it has long communication distance and good conflict prevention performance. It is generally used in parking lot and logistics

2.4G: RFID card reader in microwave section, with strong penetration, is the first choice of automatic intelligent equipment

5.8G: RFID card reader in microwave section, which is used in etc electronic toll collection system of expressway. At this time, the reader is also called RSU (road side unit)
