Radio frequency identification reading by using error correcting codes on sets of tags

A computing system to enhance reading of information stored on electronic tags, the system comprising:

• a plurality of electronic tags each associated with a corresponding identifier from a plurality of identifiers;
• a reading device to send a first request to read, from the plurality of electronic tags, the plurality of identifiers, and a plurality of portions of a message encoded by applying an error correcting code (ECC), wherein the message contains the plurality of identifiers;
• the reading device to receive a subset of successfully read identifiers from the plurality of identifiers and a subset of successfully read portions from the plurality of portions of the encoded message, wherein the subset of identifiers and the subset of portions are associated with a subset of successfully responded to the request electronic tags from the plurality of electronic tags;
• a decoding component to reconstruct the message by applying the ECC on the received subset of the plurality of portions of the encoded message;
• based on the reconstructed message, restore the plurality of identifiers including an unsuccessfully read identifier associated with a tag of the plurality of electronic tags;
• and
• determine the unsuccessfully read identifier based on comparison of the subset of the successfully read identifiers with the restored plurality of identifiers;
• and
• the reading device to send a second request to read the unsuccessfully read identifier from the tag associated with the unsuccessfully read identifier, wherein the second request includes a separate individual query to the tag that is based on the restored unsuccessfully read identifier.

A non-transitory machine-readable storage medium, having instructions therein that when executed by the machine, cause the machine to:

• send a first request to read, from a plurality of electronic tags, a plurality of identifiers associated with the plurality of electronic tags, and a plurality of portions of a message encoded by applying an error correcting code (ECC), wherein the message contains the plurality of identifiers;
• receive a subset of successfully read identifiers from the plurality of identifiers and a subset of successfully read portions from the plurality of portions of the encoded message, wherein the subset of identifiers and the subset of portions are associated with a subset of successfully responded to the request electronic tags from the plurality of electronic tags;
• reconstruct the message by applying the ECC on the received subset of the plurality of portions of the encoded message;
• based on the reconstructed message, restore the plurality of identifiers including an unsuccessfully read identifier associated with a tag of the plurality of electronic tags;
• determine the unsuccessfully read identifier based on comparison of the subset of the successfully read identifiers with the restored plurality of identifiers;
• and
• send a second request to read the unsuccessfully read identifier from the tag associated with the unsuccessfully read identifier, wherein the second request includes a separate individual query to the tag that is based on the restored unsuccessfully read identifier.
