I have a collection of phone cards. Is it possible to use your program for it?
Sure, you can use latest CollectionStudio 3.48 for tracking phone cards. To do this you should select "Custom collectible" option during creation of the new document in CS using "New collection" dialog. See our online help for more details how to create your own collection type and ask any questions if you will have them.

Also, in the new version (which will be release during the next week) you will have a very good possibility to import all your data from csv or xml file (of course if you have such data for example from Excel).
Also, please do not hesitate to suggest any improvements for next release for best fit of your requirements in tracking phone cards or something else.
