If you create a business card for your client in Fiber and you will need his personal information. In that case, you need all the information, including email and other phone numbers. What do you do? So if you tell him straightforwardly that the information for your business card will be broken by the Fiber Rules. If you say on the opposite side that your details give me your Business Card please provide me with your details. In that case, you do not break the Fiber Rules. So you can use this information as details, not as information.
