Barcode scanners can come in varies types - from the typical Handheld barcode to the more luxuries portable terminals used for retail and stocktaking.
Light Emitting Diodes (LEDs) have several strong attributes as a type of barcode scanners. LEDs are designed to be installed where space is at a premium. They operate at a short distance from the barcode. They have much longer life and are not affected by shock or vibration, as in the case in laser diodes. LEDs are available in several different wavelengths, in both the visible and infrared spectrum, making it possible to tailor the wavelength of the light source to the application.

Select the method that the barcode scanner can operate. Wired scanners are generally cheaper and do not require batteries in order to operate. While a wireless option will be more expensive, may require the battery to be constantly recharged but does afford the user more freedom. Wireless is now the preferred standard for stocktaking scanners for warehouse managers.
