The best thing about digital mortars are its features like auto geofence setup which helps to track sales by location so it's really helpful for companies who have multiple locations or stores across different cities/states etc., also they provide analytics reports with their service hence you can easily know where your customers go around within store as well what products do most people buy from specific area & when did those purchases happen? Also there isn't much i dislike but sometimes if someone doesn’t want his information being tracked then he might feel uncomfortable while shopping at my local grocery chain.
