Consent to collection means agreement after the Act's notice has been given; consent to use beyond the specific purpose must be a separate expression of will after the other purpose, scope and consequences of agreeing or refusing are explained (ER 15 requires it to be clearly identifiable and confirmed where it sits in a wider document). Where notice under Article 8 has been given and the person provides data without objecting, consent to collection is presumed. The collector bears the burden of proving consent, and written consent may be given electronically under the Electronic Signatures Act.
