PCs today are commodities with little differences between brands except for logos and prices. When it comes to interactive kiosks, however, product selection is both complicated and critical to project success. For a good example of how to choose the right kiosk, check outside the meeting rooms at a large New England university. (I can’t name it here, but you know the school.)

Unattended kiosks should be sturdy, easy to install, and have consistent BIOS for the life of a project. For this project, a software company supplied the university with an event-management system. This involved installing small custom kiosks to serve as automated “room card” displays outside each of the meeting rooms in a conference area of the university’s student center. Thanks to the EMS, students walking down the hallways could tell at a glance what meetings were in progress.

The original kiosks were the only units available with the application programming interface (API) needed to integrate with the EMS. But they also had a drawback—they used 5V DC power and had to be within eight feet of an electrical outlet. The prohibitively high cost of installing additional outlets meant that most of the kiosks were situated beyond eight feet. Not surprisingly, this led to continual hard-drive failures. Worse, performance was very slow and the kiosks were prone to overheating. The kiosk vendor didn’t offer repair services, either.

Looking around for an alternative to these troubled room-card kiosks, the university settled on the Pricechecker unit from Micro Industries. Our retail kiosk might sound like an odd solution for an academic setting, but it worked extremely well. The Pricechecker is a hardened kiosk with a patented passive cooling system to keep it from overheating. Power Over Ethernet Plus means it can be placed as much as 300 feet away from an outlet. The Pricechecker also has consistent BIOS to ensure that the applications won’t be affected when new units are added.

The university developed a simple graphical user interface (GUI) to replace the first application. (It helped that the EMS had a well-documented API.) Today, the university says, its Pricechecker kiosks not only provide rock-solid performance, they’re also less expensive and have larger, brighter displays than the original units.
Clearly, not all kiosks are created equal. A kiosk that combines ruggedness, performance, style and price come only from a company that designs, manufactures and sells it directly to the user—a company like Micro Industries. Give us a call sometime.

When it comes to computers “HOT” isn’t necessarily a good thing. Heat is the major contributor to computer system failures whether it’s from a power supply, a CPU fan or hard drive. Prolonged exposure to high temperatures will cause these devices to fail and take down your system. In a retail environment computer systems are subjected to conditions that significantly increase the probability of failures due to heat, therefore when selecting a computer system for an interactive digital signage application there are a few things to consider.

Today’s retail computers, digital signs and retail kiosks are designed to run under a very specific set of conditions. They’re expected to be in operation about 8 hours a day in an office or home environment (with typical temperatures ranging from about 60 to 80 degrees Fahrenheit) without a significant amount of dust or debris in the air. If you deviate much from these conditions, you can significantly reduce the life of a computer.

In a retail environment computers are expected to run as much as 24 hours a day reducing the life expectancy of a typical retail computer to about 1/3 of its normal life expectancy. Most in-store computer systems are hidden away in cabinetry or fixturing or are hung from ceilings where the temperature could be as much as 20 to 30 degrees above ambient conditions. Retailers are also very susceptible to the impact of dust, from exposure to the outside, from cardboard boxes and even generated from receipt printers. This dust is drawn into the computers by fans and can significantly reduce the efficiency of the computers cooling systems eventually causing critical components to overheat.

To compensate for these issues computer component manufactures like Intel have designed thermal failsafe mechanisms into their chips like the Intel® Core™ i7 processor to protect the CPU in the event that the chip is subjected to temperatures outside its normal operating range. This minimizes the damage to one of the more expensive components in the system but it doesn’t prevent damage to other key components like the power supply, processor fan or even the disk drive where all of the systems application programs and data are stored.

When evaluating computer systems for a retail application the primary criteria for selecting a system should be the ability of the system to deal with the environmental stresses in a store.  A number of vendors like Micro Industries have developed “Retail Hardened” or “Ruggedized” computer systems that can survive in typical store environments. This typically involves using more expensive passive cooling technology, industrial grade components and mobile or solid state disk drives. All of these factors increase the cost of the system compared to standard retail computer systems but it will minimize the amount of downtime that a retailer will experience and downtime in retail translates into lost sales opportunities.
