Use box sizes in Mi-Forms Designer for constrained text (CTEXT) fields that are recommended for your hardware device. Use character constraints where possible (constrain fields to alpha or numeric or another appropriate character subset). Consult your Mi-Forms Designer documentation for more details. Note that the use of lowercase “a", “n”, or “x” when assembling the field template are different than the use of capital "A", "N", and "X". “10A” and “10a” are very different to the recognition engine as the lowercase allows all symbols in addition to alphabetic characters. We recommend using uppercase in basic field templating except where symbols are truly necessary.
