If the user is a minor, the terms of use of the facial recognition payment service must be reviewed in advance through the user's legal guardian, such as a parent or guardian, and the user's prior consent to use of this service is required. However, users who have registered credit cards but do not have a credit card in the minor's name or in the minor's name as a family member, and users who have registered with Myakupe! but are under the age of 13, cannot use this service.
