摘要:
The invention relates to a method for verifying the authenticity of a franking note placed on a postal article. According to the invention, cryptographic information contained in the franking note is decoded and used for verifying the authenticity of the franking note. The inventive method is characterized in that the reading unit graphically records the franking note and transmits it to a verification unit and in that the verification unit controls a sequence of partial tests.
