As you can see from my photo, my "collection" of library/ loyalty cards is as thick as my wallet. My wallet is falling apart. 

I carry an android phone so I gave lemon wallet a try. As the digital card software firm is US based, most of its supported services are for US companies (e.g. Costco wholesale). There's a general lack of support for Australian based businesses. 

That being said, other membership cards (e.g. library cards) which I only need the membership number, it's good enough for now.
