Why are barcode readers with serial ports more commonly used than those with Ethernet ports?

The preference for barcode readers with serial ports over those with Ethernet ports can be attributed to a combination of factors, but one key aspect is their cost-effectiveness. Barcode readers equipped with serial ports are generally less expensive than their Ethernet counterparts. This cost advantage is significant for many businesses, especially smaller operations that may have tight budgets for equipment.

Serial communication is a long-established technology, widely supported in various applications and industries. Consequently, the components and manufacturing processes for devices utilizing serial connections are more mature and economical, leading to lower prices. Additionally, ease of use and simplicity in deployment make serial-port barcode readers attractive alternatives for businesses looking to implement basic scanning capabilities without incurring substantial setup costs associated with Ethernet systems.

While other factors such as speed, features, or compatibility might influence equipment choice, the affordability of serial port readers remains a primary reason why they are more commonly used in various environments.
