Barcode and RFID Technologies: Automatic Data Collection and Storage in Businesses


In today’s business landscape, companies are turning to automatic data collection technologies to enhance efficiency and gain a competitive edge. Among these technologies, barcodes and RFID (Radio-Frequency Identification) play a crucial role in optimizing processes, reducing error rates, and improving storage management.

Barcode Technologies

1. Scanning Pens Scanning pens operate by physically touching the symbol. The scanning motion provided by the operator scans the symbol with a beam of light, processing the information.

2. CCD Readers CCD readers capture the image of the symbol for code resolution. The image of the symbol, subjected to light, is transferred to a detector, which transmits the data to the system for code resolution.

3. Laser Diode Scanners Laser diode scanners, the most widely used technology, typically perform scanning motion through internal electromechanical systems. They use a laser beam for remote scanning.

4. Printers Barcode printers are specialized models that can directly adhere to products or print adhesive barcode labels. There are various brands and models available in the market.

Wireless Data Collection

One of the rapidly evolving segments in automatic data collection is wireless data collection. RF (Radio Frequency) technologies form the foundation of wireless data collection systems, categorized into Radio Frequency Data Communication (RFDC) and Radio Frequency Identification (RFID).

1. RFDC Systems These systems utilize portable interactive barcode readers and are highly effective in picking and placing materials stored on shelves.

2. RFID Technologies RFID is a technology that identifies objects through radio frequencies. The RFID system comprises three main components: a tag, a reader, and an antenna. This technology offers an alternative to barcode systems and can overcome issues like contamination and painting.

Steps in Barcode and RFID Technology Application

  1. RFID reader antennas continuously emit electromagnetic waves.
  2. The identity information received by antennas is transmitted to the RFID reader.
  3. The RFID reader conveys acquired identity information to an intermediary unit.
  4. The intermediary unit processes and converts the information into the desired format.
  5. Product identity information is transferred to the company’s information systems.

Advantages and Selection Criteria

Barcode and RFID technologies offer several advantages to businesses, including cost savings, portability, quick scanning, and increased flexibility. However, it is crucial to consider factors such as label cost, reading distances, and government regulations when making a choice.

Storage Technologies and Automated Storage Systems

In addition to barcode and RFID, storage technologies play a significant role. Systems like block stacking, selective pallet racks, and drive-in racks are effective in storing and managing materials.


In conclusion, businesses can optimize their processes, reduce error rates, and gain a competitive advantage by using automatic data collection and storage systems. Barcode and RFID technologies provide successful solutions in this area, contributing significantly to the success of businesses.
