4. Be flashy! Kiosks should almost always be flashier with fancier decor than surrounding stores. This gives you an air of excitement and importance. Your livelier decor will turn eyes away from big name stores and toward your kiosk. If allowed, play music that matches the style and theme of your kiosk. Have video that provides even more sensory stimulation for customers to notice and enjoy.
5. Go deep. You may only sell sunglasses, but stock a LOT of different styles. Larger stores are going to carry a wide variety of items but only a few models of an item. You, by contrast, can just carry one item, but present 70 different styles. When a customer wants a specific look, capability, or solution, your kiosk may be the only store in town that carries it.

By all means, your retail mall kiosk needs an excellent Point of Sale system. You should accept all major forms of payment and be able to process payments very quickly. Kiosks often specialize in impulse buys. Having a fast and easy POS system can make a big difference in sales.
You can also get full access to a mountain of reports and statistics via your POS. These will help you manage your employees for maximum efficiency. You also know which of your products are red hot and which need to be promoted or moved.
