Z cards are a modeling version of business cards and like a portfolio they show your versatility and scope as a model. Unlike your portfolio that will stay with you throughout your career as a model, Z Card can be handed out and left with potential clients and agencies.
A Z card will generally include around 4-6 images of different looks and styles along with your statistic i.e. height, age, dress size as well as your main contact information.
Z cards have been around for many years and are very popular with professional models as a means to market them into modeling work.
Modeling agencies often display Z Cards: this is a great way of advertising your skills to potential photographers, art directors, as they can keep your Z card and have you in mind hopefully for their next up and coming projects.
Like a portfolio the images must be of a professional standard.
