Description

  The present invention relates to a data communication system using an optical information reader.

  Conventionally, as a technique related to a data communication system using an optical information reader, a personal identification device shown in Patent Document 1 below is known. This personal identification device converts a patient's personal data into a two-dimensional bar code, affixes it to a verification object such as a blood bag or medical chart, and verifies it again with the patient's personal fingerprint.

  In this personal identification device, first, the barcode of the worker label on which the worker identification number and the like are recorded is read by a code scanner built in the device main body, and the worker is registered. Then, the worker converts the patient's individual fingerprint information, personal information, and attribute information into a two-dimensional barcode, and affixes the two-dimensional barcode to the object to be verified. In addition, the patient's individual fingerprint information is read in advance and encrypted and registered in the apparatus. Next, in the collation work, the barcode of the worker label on which the worker identification number and the like are recorded is read again by a code scanner built in the apparatus body, and the worker is registered. Then, the two-dimensional barcode of the object to be verified is read to decrypt the code, and verified with the newly read patient's individual fingerprint information. This prevents unauthorized use by an unauthorized user different from the registered worker.
