A method and apparatus provide physical verification of a correct association between information printed on a closed face package and material and/or information contained inside the closed face package. A closed face package with a document or article inserted therein has a window permitting a portion of the document to be read from a location outside of the package. A first optical device is employed to read data printed on the package and a second optical device is employed to read document data, which document data is printed on the inserted document and appears through the window of the package. A data file is read to access account information stored therein corresponding to the document data. The accessed account information is compared with the package data to determine whether a matching association exists between the package data and the document data. If the matching association is determined to exist, the package is allowed to be further processed. If the matching association is determined not to exist, the package is prevented from being further processed.
