Here you can enter Card Numbers (magnetic stripe values), to be able to scan the cards at Point of Sale. The card number can be linked to a staff member,
customer or a contact from the CRM module. Depending on the link type, the correct action will be taken at POS, that is,
staff log on, change customer for the sale, or link contact to the sale.
Note that the Allow Staff/Loyalty cards field must be active in the functionality profile to enable
magnetic cards.
