“Recently, when writing a check, it occurred to me that requiring the amount to be given separately in both words and number was a simple and ingenious solution to the problem of reducing error. It is possible, if your handwriting is as sloppy as mine, to write a letter or number that can be misread as a different letter or number. If redundancy consisted of writing the amount of the check twice as numbers or twice as words the same error could appear in both versions. It is a great deal less likely to make two errors, one in letters and one in numbers, that happen to produce the same mistaken result.” (12/22/24)
