Here are the descriptions:
Age verification: When a website asks you to show an ID document like your passport or driver’s licence to prove how old you are.
Age estimation: When a website uses a technology to guess how old you are based on things like your face or behaviour.
Age inference: When a website asks you to provide information that you must be a certain age to possess, such as a marriage certificate or credit card, to check how old you are.
Age gating: When a website asks you to enter your date of birth, or asks whether you are 18 years old or above.
Identity verification: When a website asks for proof of who you are, like showing your ID, to confirm your identity. We sometimes refer to this as ‘100 points of ID’.
