Sensors vs. Scans -- Whose Side Are You On?

On the latest episode of my all-time favorite TV show, Shark Tank (Breaking Bad is a close second), the company ( was featured. Some QR code scanning thing that was looking to raise at a $20 million post-money valuation. 

Investor Mark Cuban rejected the company largely on the grounds that he did not believe in QR codes or scanning technology in general, but was more bullish on sensor technology. Sensors tend to be more implicit rather than explicit, and involve a significantly different user experience. Examples of sensor apps include breathalyzer apps as well as what will emerge on the iPhone 5S, effectively a platform for sensor apps.

While I think both sensors and scans can co-exist, I agree with Cuban in that sensors are a much better opportunity in all regards: ultimately it will be a bigger market, and it strikes me as more nascent at present. 

RFID is a technology I would regard as especially interesting here, as if I am interpreting it correctly, it strikes me as having both sensor and scanning capabilities. Of course kooks have long been wary of RFID chips and the alleged conspiracy to implant every living creature with an RFID chip that will allow their lives to be controlled by a centralized institution. Dr. Katherine Albrecht’s book Spychips is a must read for those interested in RFID.
