Embodiments automatically select one of the multiple pre-generated payment cards provisioned on a mobile device. The multiple pre-generated payment cards (real or virtual) may each have a different credit limit. The mobile device may automatically select one of the multiple payment cards based on a transaction value of a transaction that is being conducted. An available credit limit of the selected payment card may be equal to or slightly greater than the transaction value. In some embodiments, the available credit limit of the selected payment card may be closer to the transaction value than the available credit limits of the remaining payment cards. In some embodiments, the different payment cards may be provisioned in a chip-and-pin based smart credit card or mobile wallet.
