To save space, credentials are typically listed as abbreviations on a business card. Generally, the abbreviations are appended to the end of a person's name, separated by commas, in the order of importance.
Abbreviations for educational degrees and professional licenses, certifications, designations and affiliations are industry standardized, so they are easily recognizable when used on a business card. While business cards can be formatted however the user prefers, standard professional practice suggests listing the abbreviations for advanced degrees, such as MS or PhD degrees, immediately after the last name, followed by the abbreviations for professional licenses or certifications. Abbreviations for important affiliations can be listed thereafter.
