Put an enlarged QR sign near the road in front of your company so people driving by can scan it to their phones and be led to the company website and its slideshow or products or services. This may work especially after hours when people are interested but do not want to wait another day. Test the size and the link to make sure it works without problems, and with ease.
Always make it worth the time for a visitor, otherwise, you send the opposite message. Be sure the information is pertinent and captures the attention of the guy who took the time to inquire about your firm. If he goes to this trouble, make it worth his while. Successful QR Code campaigns normally reward the scanner, so offer a discount coupon, helpful list of free suggestions, important and exciting links or something else of perceived value for anyone who scans your company sign. Maybe take the opportunity, if he signs up, for ongoing emails from your company to enter him into a promotional contest that is drawn every week or month.
Remember: You must always reward the person who takes the time to show interest in your products, service and your firm. If you disappoint, you will not get to do it again. Do not ruin your own advertising; make it worth the effort to find your website.
