    Patent number: 10624569
    Abstract: A blood glucose test strip includes a test strip, a blood test area formed on a first end of the test strip, an electrode formed on a second end of the test strip, a data barcode formed on the test strip, and a clock code formed on the test strip. The data barcode may include a plurality of first bars with spaces separating the first bars, each first bar having a width. The clock code may comprise a fixed pattern of second bars with spaces separating the second bars, a width of each second bar set according to the width of at least one of the first bars.
