I am thinking to add an ic to controller these to serial ports, but I don't know which type of IC I should used!! could any one help me, please?
Thanks,
Firstly, a customer pulls one smart shopping cart from the shopping cart line. When an item is picked, it is scanned (using the item’s bar code) before placing inside the shopping cart which in turns sends a wireless signals to the main cashier computers informing about the purchasing progress. ... the customer scanning an object and THEN deciding not to buy it?
is this a school project or an industrial application?
