10 Coolest Tech Gadgets to Seal the Deal

8. Moo.com Business Cards (50 business cards start at $20)

If you think you can close that deal without effective paper business cards, think again. The trick in the modern age, though, is to get the right card to the right customers. That means customizing your cards as needed and printing in small batches.

For my money, Rhode Island-based Moo offers the best on-demand card and collateral solution out there. Need a basic yet cool card for that hot new prospect? Go to Moo's site, design your the card perfect for that lead and voila ... the cards show up in the mail. It's tremendous.

For better results, I prefer to hire a designer to create a portfolio of design options for a Moo account. Upload your company logos and other material and cut, paste and customize as demanded.

Clients keep cool cards. Moo is perfect way to make cool cards. You do the math.

9. Polaroid Grey Label Instant Mobile Printer ($99)

Polaroid may have bumbled into the greatest brand niche in desktop printing history. Its Grey Label printer is essentially the Instagram of printing -- a clever portable printer that renders fascinating-looking printed images basically on demand. The 15-ounce unit works with any smartphone, tablet or mobile device. Take one of those simply awful smartphones pictures, flow it into the unit, press "print" and ... poof ... out comes a terrific-looking instant print. Really, anything looks great: reference shots of product, snapshots of you and your customers, even the most basic snapshots. With a bit of imagination, you should find that a printed-on-the-spot image is heck of way to get customers to remember you.

If you are looking for clever way to put a little zip in your mobile sales, printing up a bit of business memorabilia works. And so does this Polaroid.
