Even in our modern age, it's still necessary to have paper copies of birth certificates in most countries, provinces and states. There are three types: long form, short form and wallet sized. The long form tends to provide more information and include signatures of the doctor and parent(s). Short forms are not usually considered an actual certificate, but are seen as proof that a certificate existed. Wallet forms are similar to short forms but smaller sized.
Some American states have begun to use an Electronic Birth Registration system where all birth information is only stored in computer databases eliminating the need for paper certificates.
