POS machine terminal decoding library authorization code verification method

Abstract

The invention discloses a POS machine terminal decoding library authorization code verification method. The method comprises the following steps of: firstly obtaining a unique hardware identificationcode of a POS machine, encrypting the unique hardware identification code into a 256-byte license file, and writing the license file into a hardware information storage read-only partition; starting up the POS machine, obtaining the unique hardware identification code from the hardware information storage read-only partition by a system communication module, writing the unique hardware identification code into a system hardware recognition code registration table, and appointing a read-only attribute for the system hardware identification code registration table; reading the license file in the hardware information storage read-only partition by the system communication module, writing the license file into a system installation information catalog, and setting a read-only attribute for the license file under the system installation information catalog by the system communication module; and finally starting a POS card swiping program, and verifying the license file in the system installation information catalog and the unique hardware identification code in the system hardware identification code registration table by the card swiping program.
