    A personal check was cashed by a local merchant in the amount of $200.00, but when the check was eventually processed by the bank, it reflected only $2.00. The subsequent investigation and research verified the use of an easily accessible disappearing ink that is commonly used throughout the United States by numerous people. This paper will trace the method involved in executing and also detecting this particular type of fraud. The strengths and weaknesses in detecting this type of activity will also be discussed as they pertain to the questioned document examiner.
