Portable Scanners: 5 Fast Facts

Fact #1. The image scanner as we know it today can be dated back to the middle of the 20th Century. The first functional computer linked scanner was a drum scanner. This is a device that uses an acrylic cylinder to which the document or photograph to be scanned is fixed. The cylinder rotates before a series of optics called photomultipliers. These capture the contrasts and colors of the images whirled before them, faithfully recreating the image scanned in detail.
Fact #2. Today, a digital camera often plays the role a scanner occupied a few short years ago. Many smartphones now use their built-in cameras to create a verisimilitude of a scan, as well. That said, to create truly high quality, crisp and clear scans, an actual image scanner is still the ideal choice. No longer are these units large and unwieldy, nor are they complicated to use. The portable scanner comes in two basic designs: the roller-fed option, and the glide-over option.
Fact #3. These devices may seem like a luxury to some people, and like an absolute necessity to others. The chances are good, however, that almost anyone actively participating in the modern world can find at least a few uses for one. For those involved in law enforcement, forensics, or field research, these items can greatly simplify investigative work and data collection.
Fact #4. Of course, most people use these machines for much more quotidian purposes. That renders them no less useful. They're a great asset to anyone in human resources or recruiting who wishes to make quick copies of business cards or resumes. They're also perfect for those manning a booth at a job fair, when the hardware usually at one's disposal in an office must be left behind.
Fact #5. The price range varies widely from one portable scanner to the next. Consider your specific needs before you start to consider specific units. This'll avoid any reticence to buy caused by sticker shock. Not all models are created equal, and not all are capable of accomplishing the same tasks. Make sure to choose wisely and spend as needed.
