Corded vs Cordless Scanner: Which One to Choose

Corded means the scanner is tethered to its host by a cable. Modern cables are almost always USB, though older POS terminals sometimes still use RS-232 serial. The same cable supplies power, so there is no battery to charge.

Cordless means the scanner sends its reads without a cable, usually over Bluetooth, either straight to a laptop, tablet, or phone, or to a cradle. The cradle is a charging dock that doubles as a receiver, and it is the cradle that plugs into the computer over USB.

On the computer side, both types usually work in keyboard mode (HID, or keyboard wedge): each scan appears as if it had been typed into whichever field is active. That is why a scanner works in Excel, a POS app, or a web form with no special driver. For specific applications, a scanner can also be set up as a virtual COM port.

Reading technology, 1D laser or 2D imager, is a separate question. There are corded and cordless versions of both, so decide which symbology you need to read first, then choose how the scanner connects.

Most cordless scanners can be set to one of three modes.

Bluetooth range depends on the radio class: Class 2 covers about 10 metres, while Class 1 can reach about 100 metres in open space. Metal racking, concrete walls, and the operator's own body reduce real-world range, so check the specification of each model and test on site.

Choose corded when the scanner always works at the same spot:

• Retail and F&B tills, with the scanner sitting beside the POS.
• Event registration desks scanning QR tickets from attendees' phones, for example with a 2D imager such as the Zebra DS2208.
• Goods-receiving and data-entry desks, including presentation scanners that stand on the desk and leave the operator's hands free.
• Multi-day events, because there are no batteries to recharge every night.

If you only scan printed 1D barcodes on a tight budget, a laser scanner such as the Honeywell Voyager 1250g is enough. A corded scanner has only one real drawback: the operator cannot reach anything further away than the cable allows.

Choose cordless when the operator has to walk or the items are too big to bring to a desk:

• Stock-takes on high racking and in large warehouses.
• Bulky items, such as cartons, water gallons, or goods on a trolley that cannot be lifted to the till.
• Long queues cleared by staff walking the line (line busting) in shops or at event check-in.
• Production areas where a cable could catch on machinery. For harsh environments there are rugged models such as the Zebra DS3678.

The cordless version of a popular corded model usually shares the same scan engine, for example the Zebra DS2278 for 2D or the Zebra LI4278 for 1D. That lets you apply the same symbology and suffix settings to corded and cordless units at one event.

Tips for multi-day rentals: give each scanner and its cradle the same number label so pairs never get mixed up, charge cordless batteries fully every night, and keep one spare unit for each group of tills. Units are listed on the barcode scanner rental page, rate ranges are on barcode scanner rental prices, and 2D reading technology is explained in the glossary entry 2D area imager.
