A model card is a model's handbook, ID card and letter of introduction, which can be used when applying for a job and introducing models. Its contents include the model's body shape data, such as height, weight, measurements, the company the model signed with and several representative personal photos. In order to protect the interests of the agent, there is no mailing address and telephone number of the model himself on the model card.

To show the best image and the most infectious moment of the model between square inches, it takes a lot of thought to choose photos. If the five senses are very distinctive, then a close-up of a frontal head portrait is very convincing. If the legs are slender and stylish, then the miniskirt is a good costume prop.

Often a beautifully made model card will bring unexpected opportunities to the model who has not made a debut in job hunting.

In most international metropolises, there are many model cards in the reception room of fashion model agencies or fashion show production companies, and customers can choose some to take away with their consent. In such companies as Shanghai and Beijing, model cards are only provided to customers who have a clear intention to sign contracts.
