If your Walk-In or Dine-In customer does not have their mobile phone, or has it set to Do Not Disturb, they cannot receive the 4-digit redemption code and hence cannot redeem loyalty for that particular order.

However, if the customer can access the email receipt that has the redemption code, they can successfully redeem loyalty on that order.

Update a customer's email address on the customer profile in CRM to enable this feature.
