Value Representation and Notation

For value representation of data objects, the following notation is used:

• Characters included in the Merchant-Presented QRC are enclosed in double quotation marks, for instance "Test@123".

• A character can be represented by its hexadecimal value. Single quotation marks are used to indicate the hexadecimal value, for instance '42' to represent the character “B”. 

For the presence of data objects, the following notation is used:

• M: Mandatory – shall always be present. 

Note: If the Template, e.g., Merchant Information - Language Template, is present, then the data objects that are labelled M shall be present in the template. Otherwise, the whole template shall be absent.

• C: Conditional – shall be present under certain conditions. 

• O: Optional – may be present.
