Square places a premium on account security, both for your business and your customer. In order to help limit the number of fraudulent charges on your account, which can be costly to a business, Square enforces an Email Verification as part of the payment process. This applies to Appointments and Gifts and Packages. Full Slate has an email verification step in place that supports this additional security layer.
First-time clients will be instructed to verify their emails via a message sent to their email address listed in their purchase. They will have ten minutes to complete this process. Once they have opened the email address labeled "Instructions to finish..." they will then be prompted to complete their appointment booking process or purchase of a gift/package.
