In the animation, there are 10 postcards coming in the mail. Each one carries a trading card (symbolized by a color - different color for each card in the set), which the recipient removes and adds to his/her collection (by laying the card in a pattern on the desktop). The InsetCards custom exchange website (symbolized by the computer terminal) automatically registers each card sent. When a trading card is received that is already in his/her collection, the trading card collector goes to the website and performs a trade. He/she also trades the collectible trading card by exchanging it in the mail. Having a complete collection ends this animation but collectors may continue to trade and collect other (more valuable versions of their cards) and/or other sets of cards.
