iMerchant has two barcode identifiers for customers,"CID", and "CAU".

• CID: When a barcode begins "CID" the next digits are assumed to be the customer ID.
• CAU: When a barcode begins "CAU" iMerchant automatically searches the Customer Authorized User list for a match of the barcode including the "CAU" prefix.
  • This was created so that a store can purchase cards that are preprinted with the CAU prefix and a unique sequential number. The user can then add this card to the Authorized User list for a customer.

The following programs will use the CID and CAU prefixes and automatically identify the scan as a customer scan and perform the customer lookup:

• Customer Find
• POS
• Customer Order Find
• Customer Order Detail Find

Customer Find supports scanning of non-standard barcodes. Since customer cards from an old program might exist, the barcode information from these cards can be entered as the Customer Short name or as a Customer Authorized User.

Customer Find Scanning rules - iMerchant will make the following attempts to find a customer based on the scanned data:

• If an iMerchant identifiable label is found such as a Customer Order, Customer Order Detail, or Customer ID or Customer AuthorizedUser the customer is extracted and the search is complete.
