A method for identifying a radio frequency (RF) tag is illustrated. The method includes receiving a user input pertaining to a data portion to be searched in one or more RF tags and a semantic information associated with the data portion, determining an encoding scheme based on the semantic information associated with the data portion to be searched, encoding the data portion using the determined encoding scheme to generate an encoded data portion, transmitting an interrogation command to the one or more RF tags, and receiving the response signal from the RF tag.

Systems and methods for encoding and decoding data

An encoding method is illustrated. The method includes receiving data to be encoded onto a storage media, wherein the data corresponds to an item and is assigned to a data category. Further, the method includes parsing data into a plurality of data portions, based on one or more first characteristics associated with each of one or more characters in the data. The method further includes encoding, by the processor, the plurality of data portions using a plurality of encoding schemes, to generate a data packet, such that a first data portion of the plurality of data portions is encoded using a first encoding scheme of the plurality of encoding schemes and a second data portion of the plurality of data portions is encoded using a second encoding scheme of the plurality of encoding schemes, wherein the first encoding scheme is different from the second encoding scheme. Furthermore, the method includes transmitting the data packet, wherein the data packet is configured to be stored in the storage media.

Various embodiments of the present disclosure identify radio frequency identification tag(s) and/or location(s) thereof. Embodiments may perform such identification utilizing any number of antennas configured at various power levels and/or frequency channels, such as by incrementing and/or decrementing the power level of each antenna and measuring a number of tag reads at interval for each antenna. Confidence scores for each antenna may be generated and compared. Some example embodiments initiate an interrogation command associated with a RFID tag, cause activation of a plurality of antennas at a plurality of transmit power levels, identify a count of tag reads associated with each antenna, and determine a tag location associated with the RFID tag based on the count of tag reads for each antenna.
