carry carry / E-cards

Design motive
Nowadays we are in the so-called information explosion society: we need to meet people every day. The most efficient way to introduce ourselves is to give the business cards. Business cards are a tool to communicate and interact with others; they are just like our brief resumes in which must contain our names, positions, addresses and contact information.
We must have a sufficient number of business cards at hand, and we must not mix our business cards with others' or other stuff.
We have to keep others' business cards well so as to make use of them in the future.
