Swipe Card Screen
Go ahead and swipe a card at the main menu to
initiate a Record Sale transaction. If hand-keying the
ID off the back of a card, you do NOT need to enter
the first 4 zeroes.
If a registered customer does not have a card
available, you can enter their mobile number in this
screen in lieu of card ID#.
Swipe/Enter Card #:
The mobile number in lieu of card ID transaction will
only process if the customer has registered with their
701000000
Mobile Phone #. Otherwise, the system will return
Invalid Card ID error. An error message will also
return if the user registered more than one (1) card
with the same mobile number since the system
cannot detect which card the customer intended to
use. We recommend keeping the Max Accounts
Per Person value set to 1 in Registration Settings
to prevent customers from registering more than one
(1) loyalty account.
