Disclosed herein are systems and methods that provide a temporary payment instrument having a barcode with an encrypted account number and expiration date assigned to a consumer. For example, such systems and methods screen a consumer to determine whether he or she meets credit eligibility requirements established by a merchant card provider. If the candidate meets the credit eligibility, such systems and methods may assign a payment card account number and expiration date to the consumer, encrypt the payment card account number and expiration date, and generate a barcode that includes the payment card and account number embedded therein.
