To people who suggest "unique ids" being communicated between seller and buyer - I'm selling some shareware on the web and sometimes I'm getting emails from people who bought my software several years ago. Since then they re-formatted their drive, lost email archives, changed email address and so on. Sometimes they even have slightly different name in "From". Payment processors I use (RegNow and share*it) capture tons of information I could use to authenticate the buyer and give back their license. There's absolutely no guarantee that unique id will stay with them.
- gnud 15y agoI think the idea is that the payment processor (visa, mastercard) keeps the mapping between unique id and customer. They handle the authentication, and then gives the customer their "support number" or "receipt code" or whatever you want to name it.
