In Progress
This was mentioned in the comments of an earlier idea, but I felt it needed its own entry to be considered independently.
The Online Advancement System has a feature that allows units to print out "temporary" membership cards. Let's alter this system and enable it to be the primary method of membership card distribution. For units, the ability to print (or reprint) cards at will would provide them with a fantastic resource, and another reason to go online and start using them. For Councils, it would be one less administrative process, freeing up staff time as well as a savings in production and postage costs. For National, it would help encourage more units to use the Online Advancement system, and increase the amount and accuracy of any advancement data it processes.
Another logical step would be to allow anyone who uses MyScouting the ability to print their own membership card. This would be especially beneficial to Youth and Adult Leaders who are not registered in a traditional unit.
People like to be independent and do things themselves. We just need to give them the tools.
