Plastic card-collecting is becoming a popular hobby. Though most of them come in a standard size, the colors and designs on them make for an interesting collection.
One's collection can easily grow considering the fast pace in which shopping and entertainment outlets spring up and with it the introduction of loyalty cards. Telcos, gas, hotels and airlines also contribute to the number of plastic cards being introduced.
Let's not forget customized gift cards. Besides making great gifts, the variety of designs and colors of these gift cards would certainly delight many a card-collector.
