Industrial 4 3 matrix keypad Application:
The non-encrypted numeric keypad refers to a type of keyboard that lacks encryption capabilities for input numbers. Unlike encrypted keypads, it does not support features such as input encryption or complex key management.
This kind of keypad is commonly used in various types of inquiry machines—such as telecommunications query devices—where users can input numbers or IDs to retrieve information directly.
Due to its simplicity, the non-encrypted numeric keypad is typically employed in scenarios where information security requirements are low, such as general querying and basic operational tasks.
