Site Functionality Updates

This week, we've been working on making the site more functional. Now you can filter the full Callcard list by card type and chip type. These filters make for some very interesting facts. Heres just 3 I've got with playing around with it for a few minutes:

• There are only 17 "100 unit" Callcards, the rarest being (1017) Cork FITCE Conference
   
• There are only 19 "5 unit" Callcards, the rarest being (1044) Royal Hospital Kilmainham Stamp & Coin Fair
   
• (surprise surprise) Gemplus is the most commonly found chip in Callcards

Update: Due to site performance, we're putting the feature on hold for the moment. We are instead implementing a chip type element built into search, so watch this space!
