The invention relates to an RFID performance evaluation method based on a radio-frequency door, specifically comprising the following steps: (1) basic information modeling; (2) test model selection; and (3) performance test. Performance test includes: (1) single tag application performance test; (2) meter directivity test: testing the performance of a single-phase power meter at different angles between the single-phase power meter and an antenna; (3) single tag test in a group environment; and (4) group tag test in a group environment. The invention puts forward an evaluation method for applications in group tag and radio-frequency door scenes on the basis of traditional single tag performance evaluation.
