There will be an online application to accept product bar-code and weight until its weight is entered by the cashier so that program could display the amount to be paid. I need some information to interface the scale with this application.
Question 1: What type scales will output weight information for the application use?
Question 2: What are the means and options to interface the scale input to the application screen?
Eventually, the data will be stored in a database.
Question 3: In order not to reinvent the wheel, what systems are available in low price range?
