Types of Barcode Scanners

Find out what type of barcode scanner is most appropriate for your line of work

A barcode scanner is a device that provides an effective, safe and quick way to capture information: typically through a product code. The scanner is a key component in all bar code applications. Commonly this type of equipment is used at reception areas, in shipping, tracking, inventory, and sales. Both wired and wireless barcode scanners are sufficient for these types of applications.

Type of Connection;

Types of Readers


These are new generation readers. Info can be sent faster than previously and the connection is simple. They do not need extra power given that the power they generate with this connection is enough.

PS/2, Keyboard interface

When a Keyboard reader is required or the data must be inserted as if being typed, then what is being used is a Keyboard Wedge. This is connected to the mobile computer or to the computer's keyboard. These readers are directly connected to the keyboard's serial port and the jack is identical to the keyboard's one. They usually include an adaptor which may be simultaneously connected to both keyboard and reader.

RS232 (Serial)

Readers that connect to the RS-232 port (or serial interface) require a special software which is able to recover data sent from bar code readers and insert it where it's needed. This interface is slightly different from the keyboard and it gives us control over the code's reading destination.


Bluetooth Readers send data in real time to the PC, via wireless connection. Communication is carried out via WiFi. The devices do not need to be connected using cables and can be positioned in multiple spaces if the transmission power allows it.

RF (radio frequency)

Wireless Readers use radio frequencies to send data acquired directly from a PC or database. The main criteria to be taken into consideration when purchasing a RF reader are its reach and battery life. Wireless readers improve the reception and transmission of info in those cases in which the cable may be damaged or limit the number of products which may be scanned. RF reach is superior to BT reach


Handheld Readers


Handheld readers include wireless and cable scanners and have different scanning engines, depending on the model they are capable of scanning different types of labels. They are light and ergonomic, ideal for retail sale and inventory. These are the simplest and most economical.

Robust Readers

They have been specifically designed for industry and logistics. They are extremely robust and function perfectly in extreme weather conditions. Ideal for warehouses, both indoors and outdoors, and places where the risk of being dropped and damaged is high.


2D/PDF417 Readers


They represent innovation in the scan technology field. They are able to read a larger number of barcode symbolism and are even capable of scanning images such as signatures and defective or imperfect codes. Ideal for those environments where a correct scan must be guaranteed.

WiFi Readers


Wireless readers allow the transmission of info in real time, from scanner to database. They require W-LAN infrastructure. These readers significatly improve worker's performace thanks to their simplicity and usability.

BlueTooth Readers


These readers allow the transmission of data from the scanner to the PC immediately, in real time, without the need for a cradle or cables. No infrastructure needs to be installed, the only requirement is for the PC's database to be able to connect via bluetooth.

In Counter Readers


These readers are ideal for cash register operations, because their high-speed scan pattern allows to capture barcodes from different angles. This reader can be fixed into the counter or directly on top of it. The smaller ones may be used as handheld readers or in hands-free mode.

Fixed Readers


Fixed readers are used in categorisation operations and in high-speed applications. Small fixed readers are commonly used in labs and access control. Differently from other barcode readers, these scanners are integrated with other devices or automation systems.

OEM Readers


Original Equipment Manufacturer (OEM). These are readers which enable clients to integrate computers in their packages, boxes or systems.
