Instead of using generated codes by the system, operator could import the list of code (that could be the member number of contacts...) and use those codes as single use codes. 

How to get started:

• When generating single use codes, a new option "Import codes" is available allowing operator to upload an csv file that contains list of code to an advantage.
• Format of the csv file:
  • no header
  • one code per line
  • each code must less than 20 chars
  • only numbers and alphabetic are accepted
  • Case sensitive are ignored
• The code could be used as usual from Touch Cart and Ticket Shop
• If the length of imported codes are not 16 chars, in order to use it at fastline, please make sure you have configured this parameter: “config.voucherCode.validateRule”=FREE_MODE at the B2C point of sales internet theme
