When a business asks you to share your information with them using Yoti, there may be some bits of information (‘attributes’) that you must share, otherwise they couldn’t provide their service. We call these ‘mandatory attributes’. Other pieces of information might not be strictly necessary, and it would be your choice whether to share them. We call these ‘optional attributes’. Whether an attribute is optional or mandatory can be different from business to business, depending on the context. For example, if you were using your Yoti to log in to an online shopping site, and wanted to purchase age-restricted goods, the shopping site would probably request your age (or the fact that you were over 18) as a mandatory attribute. The business should have a privacy notice which explains which attributes they need. Some businesses will require certain attributes as Mandatory and others as Optional. Depending on what they decide and require, once they start working with Yoti.
If your document does not have one of the Optional attributes the QR code is requiring, you will be able to continue.
If your document does not have one of the Mandatory attributes the QR code is requiring, you will not be able to continue. And you will have to add a new ID to your Yoti that does have that attribute (eg: Gender, Nationality).
