The Collection module is specifically designed for handling Collection features. These typically come in the form of a sticker album, or collectibles album. With some creativity, you can re-purpose this for something else as well.
Cards
The first page allows you to configure the cards that will be in your collection. All of these are currencies that need to be created, which can easily be done via the dropdown. The weight determines the rarity of the card. In most implementations this varies.
Sets
With cards configured, you can configure your sets as well. Easily add sets and cards to each set. As is standard with a lot of these systems, gathering all cards within a set completes the set. Complete all sets, complete the collection.
Duplicates
Duplicates have 2 ways of being handled. They can be completely ignored, in which case, nothing happens in the module. Or, we convert duplicates into another currency. This is another standard practice from a lot of implementations. Simply select the desired currency and the amount.
Tracking
Tracking allows you to assign currencies to track certain things happening within the module. For example, Duplicates. They are not tracked by default, but, if you want to track duplicate items, you can assign a currency to each card. Since they are currencies, they show up in the graph view in Architect mode.
Insights
Insights is a dashboard page that shows what happens with the collection. By default, it runs a collection to completion 1000 times. Based on that, it generates results that will help you identify whether the collection is in a good state or not.
