Consent means giving permission to the collection of personal information. This usually happens in one of two ways.
●    Implicit consent means that the individual has consented based on their purchase of a ticket.  In order to buy the ticket they have to pay for it and provide a credit card number.  Purchasing the ticket is their implicit consent to the collection of their credit card number which is personal information.
●    Explicit consent is where a consent form is provided to the person.  For example, consent forms are routinely used for the sharing of personal information between medical practitioners.
