A method and apparatus provide verification of a correct association between information printed on a closed face package(100) and material (115) and/or information (117) contained inside the closed face package (100). A closed face package (100) with a document (115) inserted therein has a window (113) permitting a portion of the document (115) to be read from outside the package. A first optical device reads data printed on the package (100) and a second optical device reads document data (117) which is printed on the inserted document (115) and appears through the window (113) of the package (100). A data file is read to access account information corresponding to the document data (117). The accessed account information is compared with the package data to determine whether a matching association exists. If the matching association exists, further processing is allowed. If the matching association does not exist, further processing is not allowed.
