An "LD card" refers to a learning disability identification card or autism identification card, which helps individuals with hidden disabilities communicate their needs in various social situations. However, there are alternative terms that can be used interchangeably to refer to this important document. It may also be called a "disability ID card", "special needs card" or "accessibility card". These synonyms encompass the purpose and functionality of the LD card, as they underline the importance of accommodating and supporting individuals with hidden disabilities in order to promote inclusivity and equal access to services. Regardless of the terminology used, the ultimate goal remains consistent: to ensure that every person, regardless of their abilities, can fully participate in society.
