An authentication system authenticates various validities of a visit of a delivery surrogate. The authentication system includes an authentication card, a user terminal, and a card reader. When the authentication card is inserted into the card reader, the user terminal generates a random number, stores the random number generated, and outputs it to the authentication card. The authentication card encrypts the received random number by an identification key stored in advance, generates encrypted information, and outputs the encrypted information generated to the user terminal. The user terminal decrypts the received encrypted information by using the authentication key stored in advance, generates the decryption result, and judges whether the generated decryption result coincides with the random number stored, thereby performing authentication. |
