Dear Sir Ref. to the discussion held with under sign, the detail is as under--- We are in weighing scale field since 1986. We are assembling the scales by purchasing the material from out source ( From India and other countries). Now we decide to make our own Card in our decided shape. So we want to develop a universal card , which we can make all types of scales of up 100000 counts with 7 segment LED Display . Also with other features like Printing, Counting, RS232 Etc. And Three Pass words at different levels. And we can edit the Softwear. What else you can provide in this field, also mention. We will pay you the development , softwear and testing charges. And up-gradation charges at time to time. Our web site is modern-scales.com Kindly revert.
