Free field
When using the logo, there is a so-called "free field", in the area of which there should be no graphic elements. This space is necessary not to interfere with the correct logo perception. The font height of the logo text part is taken as the measurement unit to calculate the free field. Everybody who is using the logo must follow this rule.
Minimum allowable logo size
The minimum size of the logo is determined by the "payment processing system" font size. The font of this logo part mustn't be less than 6 pt. If you need to use a smaller logo, the text block should be removed.
