This happened at my store and I do not want any retail store employee to be a victim of this fraud. We need to protect our stores, our jobs and our customers. People need to use a pigment based pen to prevent check fraud. There is a Youtube video encouraging people to use a product such as the Uni-Ball 207. There will be a link on amazon.com if people want to pick up this product if you do use checks. It is strongly recommended to deliver directly to the post office any mail that has checks if you do insist in using checks, but pay bills electronically.
