Corded vs Cordless Scanner (Corded (USB) vs Cordless (Bluetooth) Scanner) — Definition & Context in B2B Laptop Rental

This is the distinction in how a scanner connects to its host. (1) Corded — the scanner is tethered straight to a PC/POS over a USB cable; no battery (it draws power from the USB port), no pairing delay, and it is cheap. A fit for fixed scan points: retail tills, goods-receipt desks, data-entry workstations. The limitation: the operator is tied to the cable length (±1.5–2 m). (2) Cordless — the scanner connects over Bluetooth to the host or to a base cradle (a charging dock that also acts as receiver and offline data store). It has a rechargeable battery (typically one shift to several days per charge), a Bluetooth range of ±10–100 m depending on class, and lets the operator roam freely. A fit for stock-takes on high racking, large warehouses, loading docks, and roaming inventory. The trade-offs: higher cost, battery/charging management, and possible signal interference. Rule of thumb: fixed scan point → corded; need to walk or reach bulky items → cordless with a base cradle. For inventory that must run a WMS app on the device (not just send keystrokes), consider a PDT. The reading type (1D vs 2D) is a separate question from cabling — see 2D area imager.
