With respect to my previous example on biometrics, the other element that was adopted was the introduction of a family fee. Prior to the application of GBA, the fee was thought to be primarily per individual. Once the GBA was done, we quickly realized there are many parts of the world where people have much larger families, and those costs would become prohibitive. Therefore, a family fee was introduced and capped so that it was more affordable for those individuals.
