The attributes (Cf. List of attributes) are comparison criteria related to the transaction admission data.

For example, the card amount or country.

An attribute always begins with the special character "#". This convention enables the rule engine to detect attributes in the rule captured. Moreover, when this character is captured in the form, the comprehensive list of self-completed attributes is available.

Attributes represent different types of values, for example:

  • amount = whole type (a numerical value without a decimal),
  • card country = string of characters that is 3 characters long  Cf. list of attributes. 

In a rule, an attribute is always followed by a comparison operator
