Folks,
Check out this unit
http://pertelian.com/index.php
Think of it as a pole display.
It is fairly small but it makes up for it by displaying 4 lines instead of of 2. This means that the top two lines can display the current item being rung up and the bottom two lines can display the running total for the sale. It also costs about 1/3 the price of a regular pole display.
If the back of your POS monitor faces the the customer you can mount the Pertelian device on the back or top of the monitor. This would make it quite easy for your customers to read despite its small size.
I have contacted the fine folks at Pertelian about using their device as a pole display with DHPOS and they seem interested, which is good because they would have to write a driver to interface between their unit and DHPOS.
But the big question is what is your interest. Does this seem like a good idea to you and would you be interested it purchasing one or more of these devices for your store?
Don't be shy, post something.
Dale
