activation buyer code codes control delivered delivers downloads easily generate machine multiple online pay pin prevent prevents protection service single software tool transferable words

How does e-junkie make it possible that the delivered pin code (for downloads) be used only by the buyer? In other words, is it possible to prevent that the same pin code be used on and on by people that did not pay to get downloads? (are pin codes easily transferable?)

E-junkie simply delivers the codes you enter or generate. How they are used with your software is something which E-junkie can not control.

If you want the codes to be used on a single machine, you'll need to find software protection tool which provides online activation service and prevents multiple uses of a code.
