What are the differences?

There are various scanner models designed for different purposes, such as those mounted on forklift trucks, wireless handheld scanners, and fixed models used at packing stations. We’ll help you understand how to choose the best barcode scanner and highlight some top models to consider.

Choosing the best barcode scanner: the options

In the past, barcode scanners typically used laser technology. A laser beam was projected onto a barcode using moving mirrors, and the reflected light was captured and converted into data. This method is still widely used today but comes with limitations—it can only read 1D barcodes and is mechanically fragile due to moving parts. If you’re searching for the best barcode scanner today, you’re unlikely to find a laser-based model.

Nowadays, the best barcode scanners use a (CCD) light sensor, which can capture an image of one or more barcodes and extract data from them. This technology can scan multiple codes simultaneously and does not require horizontal scanning. Transitioning from laser scanners to modern imager scanners may surprise many users.

Selecting the best barcode scanner based on your needs

Determining “the best” barcode scanner requires understanding its intended use. Here are some essential questions to consider:

• What sizes need to be scanned?
  Are you scanning small labels on boxes, larger barcodes on pallets, or barcodes stamped into metal?
• What scanning distances are required?
  Consider both the maximum and minimum distances. It’s frustrating if the scanner’s “sweet spot” is farther than your arm can reach when holding a box.
• Can the application handle the barcode content?
  If the application cannot read the data in a barcode, can the scanner be programmed to convert it into a format the application can process? For example, the EAN128/GS1 Group Separator is a non-standard, non-printable character. Can the scanner convert this into a printable string accepted by the application?
• How should the scanner be connected to the computer?
  If it’s not a mobile computer with a built-in scan engine, how will the scanner connect to the computer?

Connecting the Scanner to the Computer
The first decision when connecting a barcode scanner to a computer is whether to use a wired or wireless connection. Whether a particular model is the best choice depends on your specific situation.

Wired Connection
Advantages include getting power directly from the computer, but the cable length limits the distance between the scanner and the computer. Important questions to ask include:

• Is a coiled cable practical for use?
• Does the scanner need to emulate a USB keyboard, and does it require programming?
• Will an RS232 connection be used, and can barcode settings be programmed directly into the computer?

Wireless Connection
Most wireless scanners use Bluetooth, offering more mobility and flexibility. These scanners have a built-in battery or rechargeable power source. Consider these aspects:

• What is the battery life?
• How is the battery charged, and how long does it take?
• Is the battery easily replaceable for continuous use through multiple shifts?
