A serial barcode wedge is a specialized data acquisition tool—available as either a physical hardware adapter or a software application—that intercepts barcode data from a serial port (like RS-232, COM, or Bluetooth SPP) and translates it directly into keystrokes.
It allows industrial equipment, legacy hardware, and dedicated serial scanners to dump data directly into common consumer or enterprise apps (like Microsoft Excel, Notepad, or custom web portals) without requiring any custom software modification or programming. How a Serial Barcode Wedge Works
The term “wedge” originates from the historical physical practice of “wedging” a scanner’s physical adapter between the keyboard hardware and the computer port. Today, the mechanical or virtual workflow functions through three primary stages: 1. Data Capture (The Serial Side)
When a user scans a barcode, the barcode scanner converts the optical lines into digital data. Because it is a serial device, it streams this information as a structured batch of ASCII text characters across a dedicated serial connection (such as an RS-232 cable, a virtual COM port over USB, or a wireless Bluetooth Serial Port Protocol connection). 2. Interception and Data Translation (The “Wedge”)
Normally, a standard computer operating system cannot process a raw serial data stream automatically; a program would have to actively “listen” to that specific port. This is where the serial wedge acts as an interpreter: Medium·Dino Buljubasic
