due to the getyourcode place hat only asks for the DiSa number is making me think there isn't any math to it and perhaps all they use a random number generator to assign a code and attach it to that disa number and all the merchant does is grab that code from their personal storage (merchant is given all the disa and activation codes on delivery) not having to go online to the disa server to decode anything, would make more sense and also stop any disa generators from being built to defeat them , we have a "sort of" workaround but requires a bit of more time and these projectors are not worth the time, the quality is not all that good but for the convenience of having a portable projector suites its purpose
