iDIN can be used for three different purposes: identifying, logging in and verifying. The first applies, for example, when you are going to register at a casino, as described above. At some companies, such as insurance companies, you can log in to a personal environment. Sometimes they choose to run this process through iDIN. Companies are not obliged to do this. An alternative is, for example, logging in via digID, a similar service from the government. Finally, iDIN can be used to check data. If you want to buy a state lottery ticket, you have to be 18+. This can be quickly checked with this handy service.
