card reader The 15693 protocol is a high-frequency (13.56 MHz) radio frequency identification (RFID) protocol, which widely meets the field of wireless recognition and data transmission.

Its features include far reading range, support for fast data transmission, compatibility with multiple labels, generated in different industries have a wide range of applications, including but not limited to: logistics and inventory management, manufacturing, library and archives management, access control system, medical industry.

operational principle 15693 RFID reader works 1. Activation and identification: -The reader activates the nearby 15693 tag by sending an activation command.

-The active label will respond, typically containing its unique tag ID (UID).

2. Command transfer: -The reader sends command frames to the label, which can include read, write, lock, etc.

-The command frame includes the opcode and the corresponding parameters.

3. Label response: -The label receives and parses the command frame to perform the corresponding action. The

-label responds to response frames containing status information and possible data.

4. Data exchange: -If the command involves a reading of the data, the label transfers the corresponding data to the reader.

-If it is a write command, the reader transfers the written data to the label.

5. Data analysis and processing: -The reader receives and parses the response frame of the tag.

-Resolution involves verifying the integrity of the data, checking the status code, etc.

6. Status check and treatment: -The reader checks the response status of the label to determine if the operation is successful.

-Depending on the status code, the reader may take actions such as resending a command or reporting a successful operation.

7. Terminate the communication: -After the communication is complete, the reader can send a termination command to place the label in an inactive state.

The whole process is achieved by radio frequency (RF) communication, using a high frequency band of 13.56 MHz.

This working principle allows readers to communicate with labels over relatively long distances, providing flexibility and convenience for many applications, including logistics, inventory management, access control systems, etc.
