Make your own membership cards by designing a template for use in a word processing or graphic design program and including details such as the member's name, account number and expiration date. Alternately, use an online membership card creation site such as Badgy.com to design and print the cards, as of 2015.
Begin by choosing the appropriate program for creating the design according to needs, availability and skill level, with word processing programs offering less control than graphic design programs but featuring more standard formatting options. In a program such as Microsoft Word, create a document from a business card template and modify the sections to include the appropriate areas for member names and numbers as well as other information through the use of the text editing options. This allows you to print the cards on premade business card sheets and immediately use them or laminate them for extra protection.
A graphic design program such as Adobe Photoshop allows you to set a custom document size, which could range from a single membership card to a sheet suitable for multiple cards. The document needs to have a resolution of at least 200 DPI in order to print clearly, and can include custom graphics, drawings and text.
Badgy.com offers numerous membership card templates and partners with retailers such as Office Depot, Staples and Amazon.com to handle the printing and delivery of cards, which appear on plastic cards.
