Consent to collect a customer's ID at a dealership: what you actually need

A common dealership myth is that you need signed consent for everything you collect. You do not. For a test-drive licence and ordinary customer details, the rule is to collect only what is reasonably necessary, by fair means, and to give a collection notice. Consent is the higher bar, and it applies to sensitive information, which at a dealership means things like a facial-recognition scan, not an ordinary licence or a finance form.

Two different requirements often get merged:

So for a test-drive licence, ordinary contact details, and even the income and bank details you take for finance, the requirement is usually to collect only what you need and to notify, not to obtain a separate signed consent. Finance data is high-value and needs care, but it is not sensitive information in the Privacy Act's special sense.

Common questions

Usually not a formal signed consent, provided you genuinely need it and you notify the customer. The controls for an ordinary licence are necessity and notice: collect only what you need, by fair means, and cover it in your collection notice. Better still, sight it rather than keeping a photo.

Financial information is not sensitive information in the Privacy Act's technical sense, so it does not carry the consent bar that, say, facial recognition does. It is high-value and needs strong security and a clear notice that you disclose it to lenders, but the baseline is notice and necessity, not a separate signed consent.

Most clearly when you use facial recognition or other biometric technology, which is sensitive information. That is a stop-and-get-advice decision, and consent is one of the things it turns on. For ordinary ID and finance data, notice and necessity are the rule.
