The general availability of high-quality electronic scanners and color printers for computers has made the counterfeiting of checks much easier
In order to deter such counterfeiting, several banks plan to issue to their corporate customers checks that contain dots too small to be accurately duplicated by any electronic scanner currently available; when such checks are scanned and printed, the dots seem to blend together in such a way that the word VOID appears on the check
the size of the smallest dots that generally available electronic scanners are able to reproduce accurately will not decrease significantly in the near future
