Dell sees the POS offerings as "just another addition to the portfolio", said Dell spokesman Jon Weisblatt.
The POS device, as yet unnamed, is designed for large corporations that already use Dell products in their data centres and cubicles, and want to standardise their hardware across the board.
Dell recently installed more than 1,100 POS terminals across a clothing store chain in the US.
The company's POS terminals use the existing Optiplex SX260 desktop. It can be remotely managed over a network, and is one of the smallest desktop systems offered by Dell, making it ideal for cramped checkout counters.
Most retailers run POS applications specifically tailored to their business, so Dell partnered with software vendors such as Retek, AutoGas Systems, GERS and MSS Global to make sure the client POS terminals will work with a customer's back-end systems.
For a base price of $1,794 (£1,117), retailers can purchase an Optiplex SX260 with an Intel 2.0GHz Pentium 4 processor.
