Dropcards Dollar Card Marketing 

Drop Card Marketing - https://guerillamarketing.home.blog/2019/02/28/dropcards-dollar-card-marketing/
The dropcard is unique and interesting and could easily be passed on or shown to family, friends, and acquaintances thereby creating more exposure for your business. One super amazing thing about this is that if someone picks up this dropcard thinking it is a real dollar bill and s/he is not interested in the ad, the person will more than likely toss it back on the ground where it will remain until another person picks it up.
This will certainly not happen with a conventional business card. Drop cards then become a very effective and relatively cheap means of creating awareness for your business.
