What is a Business Check-In?

When a business creates their own Herdmap marker, Herdmap users are able to check-in the the business when they are in close proximity to the marker. For every check-in, the check-in counter grows and shows how many people are there, while the business marker starts changing colors to become hotter and hotter (red). This lets users know that the business is popular and that they should stop by to check out what is going on!
