Easy Serial Number Service
I have been using my own serial number service for a while for Volko Audio and decided to turn it out a service for software vendors/manufacturers.
It manages whole serial number system easily. It generates, deposits and activates serial numbers automatically.
If you like to look at it: www.keyzy.io and let me know your opinion/feedback, would be very nice.
