RFID advantage

RFID is a flexible application that is easy to navigate, simple to use, and especially suitable for automated control. Can work freely in a variety of harsh environments: short-range RF products are not afraid of grease, dust pollution and other harsh environments, can replace bar codes, for example, used in the factory line tracking objects; long-range RF products are used for traffic, identify the distance Up to tens of meters, such as automatic charging or identification of vehicles and so on. There are several aspects of radio frequency identification system system advantages:

Convenient and easy to read: data read without light source, or even through the packaging. Effective identification of a larger distance, using the battery comes with active tags, the effective identification of distance up to 30 meters;

Recognition speed: As soon as the tag enters the magnetic field, the reader can instantly read the information therein, and can process multiple tags at the same time to realize batch identification.

Large data capacity: the largest data capacity of the two-dimensional bar code (PDF417), can only store up to 2725 digits; contains letters, the amount of storage will be less; RFID tags can be expanded according to the needs of users 10K;

Long service life, wide range of applications: The radio communication means that it can be used in dusty, oil pollution and other high-polluting environments and radioactive environments, and its closed packaging makes its life greatly exceeded the printed bar code;

Tag data can be dynamically changed: the programmer can write data to the tag, thereby giving RFID tags interactive portable data files, and write time compared to print bar codes less;

Better security: not only can be embedded or attached to different shapes and types of products, but also for the label data read and write password protection, which has higher security;

Dynamic Real-Time Communications: Tags communicate with the reader at frequencies of 50 to 100 times per second, so as long as the object to which the RFID tag is attached is within the valid range of the reader's identification, its location can be dynamically tracked and monitored
