Disclosed are a one-time credit card number based payment assistance device and a method thereof. According to the present invention, the one-time credit card number based payment assistance device and the method thereof provide a user with a randomly-generated one-time credit card number for each transaction, instead of a fixed credit card number, when the user makes a payment with a credit card. By doing so, it is possible to reduce damage to the user due to exposure of the credit card number. |
