# Update the name of an ID Card's consumer

**PATCH /id-cards/v1/business-locations/{businessLocationId}/cards/{cardId}/consumer**

Sets the first name, the last name, or both, of the consumer linked to an ID card, on this business's consumer record. Only `firstName` and `lastName` are used and other fields are ignored. A missing or `null` field is left unchanged; at least one of them must have a value.

Only placeholder consumers, whose email address ends in `@ikentoo.net`, such as the consumers created by Create ID Cards, can be updated. If the card is linked to any other consumer, the request is rejected with a 409 and nothing is changed. The consumer ID and the email address never change.
