The Loymax system has the ability to recognize external cards and provide their holders with various preferences. At the moment, this opportunity is used to work with Moscow Social Card.

To recognize Moscow Social Card, the system uses a special plugin, after connecting to which the Coupon by mask and attributes filter becomes available. In the filter are set:

• Mask by which the social card number is recognized.
• Type of filtering that enables to define the attributes of social card holders to whom preferences will be granted. Attributes indicate preferential categories of holders of social cards (for example, pensioners).

The system also enables not to indicate specific attributes. In this case, preferences will be granted to all holders of social cards whose numbers correspond to the specified mask.

 Also in the Coupon by mask and attributes filter the Result unknown type of filtration is foreseen. This type of filtering is triggered in cases where no response was received from the external system or the external system responded with any protocol error with the exception of "Card not found". Thus, if a card is recognized by the system, preferences will be given to its holder even if errors occur in recognizing the attribute of the card holder.

Thus, in the Loymax system, it is possible to configure offers for various preferential categories of Moscow Social Card.
