Scarabwins Casino has tried to fob me off with very bizarre reasons for using the *descriptor DOTASCANNER, which is a commercial business!
Non-GAMSTOP casinos will hire third party payment processors who miscode payments to and from the operator, representing to the bank or card provider that the payment is for something other than gambling. This is effectively money laundering and the financial institutions work very hard to identify transactions of this nature and ban the initiating company.
*‘Descriptors are intended to help the cardholder identify the transactions shown on their bank statements for products or services purchased’.
If the cardholder doesn't easily understand the billing descriptor and recognise the transaction, a chargeback can be initiated.
