Every single thing that you use over the course of your life will very likely have a long and storied history associated with it. It is all too common for people to assume that most of their usable items were invented in the recent past, but the reality of this circumstance is that their origins may go a lot further back than you think. For example, chances are that you think that business cards only came about in the 20th century, or perhaps the 19th century if you want to go further back in some way, shape or form.
The thing is, business cards were actually invented a couple of centuries prior. Their origins lie in the 17th century when they were first used by aristocrats to announce their impending arrival. A big part of the reason why that is the case has to do with the fact that they could drum up some excitement about their trip by sending word in advanced, and while they may not have had fancy and advanced Metal Kards, suffice it to say that their own variants were relatively similar to their modern day iterations.
Over the decades, the aristocracy lost much of its power. This power was then snapped up by capitalists who subsequently wanted to start enjoying some of the prestige and luxury that only the nobility had previously been able to enjoy. The use of business cards has remained more or less the same. They are meant to convey the status of the holder, and the more technical your card is the more obvious it would be to people that you are someone of note who should really be respected
