The present invention relates to a method for providing a barcode, and a system and an apparatus therefor. More specifically, the method for providing a barcode is carried out by issuing an individual barcode for each user, generating a combined barcode by mapping the individual barcode and a product barcode for a particular product, and performing payment using the combined barcode. Therefore, when a customer purchases a product in a particular store, a combined barcode is provided by combining card information to receive discount benefits and card information for payment, and thus the customer can conveniently use the payment service. |
