Support multi-protocol: 9801 interrgator supports ISO18000-6B, EPC Class 1, EPC Class 1 GEN 2 standard, and also support many protocols and function expanding by through upgrading interrogator's software.

Label capability optimizing: NFC serial interrgators can optimize Label's operating used far-ranging. It uses different labels' expanding function to enhance the price-quality ratio of system's applying.

Out off line function: the interrogator is designed with nonvolatile memory place. When the interrogator fail to communicate with applying suetem, it can memory identified ID Label into the interrgator to make sure the system is stable.

ID match function: the interrogator is designed with nonvolatile memory place. In a close applying system, it can memory ID Label into the interrgator in advance. When the interrogator indentifies Label ID, It can compare with the ID memoried the local PC, then depending on the result, it can run the interrgator's predefining or user designing'action.

Synchronization function: In practice, many interrgators must be installed a near place, to make sure the reliability when interrgators working, serial interrgators were designed especially with synchronization function to make sure the reliability of identifying label and reading rate.
