What Are Interface Types?

Interface types refer to the communication protocols and physical connections a scanning module supports, such as USB, TTL-232, RS232, RS485, or Ethernet. The right interface ensures seamless connection to different host systems—from POS terminals and industrial PLCs to embedded motherboards and payment kiosks .
