SELECTIVE APPLICATION OF ERROR DETECTION AND CORRECTION FOR RADIO FREQUENCY IDENTIFICATION

摘要

Methods, apparatuses, and system for performing at least one of error correction or error detection are described. In one embodiment, a radio frequency identification (RFID) tag receives a signal activating or interrogating the tag. The tag includes memory that stores data associated with the tag. The tag performs at least one of error detection or error correction on the stored data. The error detection includes detecting, by the tag, that one or more bits of the stored data are inflicted with an error. The error correction includes correcting the erroneous bit if the error affects less than a predetermined number of the bits of the stored data. The tag transmits the stored data to a reader in response to the detection or correction. The reader can analyze the stored data for additional information about the error or provide the stored data to another computing system that performs the analysis.

主权项

1. An error correction method for use with a radio frequency identification (RFID) tag comprised of an antenna and an integrated circuit (IC), the method comprising:
receiving, via the antenna, a signal for at least one of activating the tag or interrogating the tag, wherein the IC comprises memory storing data associated with the tag, wherein the stored data includes manufacturing data of the tag, and wherein the IC is configured to perform at least one of error detection or error correction on at least some of the stored data; detecting, by the IC, that one or more bits of the stored data has an error, wherein the detection is performed after the tag is activated; and transmitting the manufacturing data in response to the detection of the error.
