How to achieve mastery of various RFID tags in the hospital

Abstract

Recently, there has been an increase in the number of cases where systems using passive RFID proposed or introduced to improve operational efficiency in hospitals. In such proposals, the tag and the reader optimized for the target system are naturally selected. However, there is room for significant cost reduction through commonization of tags, readers, and antennas. At our hospital, UHF RFID tags have been introduced for blood specimen labels, and batch reading confirmation is performed. HF RFID tags are used for personal authentication and for capturing body temperature, blood pressure, blood oxygen saturation, and blood glucose levels into EMR. HF tags can be read from a distance of a few centimeters, while UHF tags can be read from several meters, depending on the wave strength. However, they cannot be read from a long distance, so common use of tags will inevitably be done with UHF tags.
