Abstract: A two layers QR code label anti-counterfeiting system includes a an outer QR code label and an inner QR code label that is arranged in a concealed manner and is paired with the outer QR code label for storage in a server. When a consumer proceeds with reading by applying an application program (APP) of a mobile phone, a QR code of the outer label is read first and after the reading, the mobile phone displays peeling off the outer QR code label to subsequently read a QR code of the inner label. The data of the two QR codes are transmitted by the mobile phone to the server for comparison with originally stored data to identify and determine genuineness or fakeness. In an attempt for determination of genuineness or fakeness for one more time or multiple times, it only needs to read the inner QR code label.
