If you scan a gift card belonging to another merchant, entering your company's 4-digit PIN Code will fail. If the other business in question belongs to the same group as your company, you can accept the gift card if their 4-digit Merchant PIN Code has been shared with you, or the 4-digit Merchant PIN Code is the same across both businesses. Please keep in mind, the payment for the gift card would still go to the bank account on file for the business that particular gift card belongs to.
