As the world marches ceaselessly forward into the future, suffice it to say that many of the things that we thought were never going to go away are starting to get replaced by items that are decidedly more futuristic from a wide range of perspectives. In spite of the fact that this is the case, not everything that is new is necessarily going to be better than some things that came before, and in some situations there is no new item that can replace the old one in the first place at the end of the day.
It is important to note that while metal business cards might not be as fashionable as they used to be during their peak of usage, they can still be relatively useful if you implement them in an effective enough manner.

Hence, business cards can come in handy in these types of circumstances, so they are most definitely relevant regardless of what people might say to the contrary. This is just one example of the numerous ways in which these business cards show their relevance in the modern world, and you would do well to be cognizant of this. Not having a business card can make you seem like an amateur and you would definitely not want anyone thinking this of you.
