POS payment screen amount input fieldby
I've a problem with one of my customers which is while in the payment screen of POS some times the barcode reader inputs a barcode in the payment field ( his customers puts the product in front of the reader) and this causes an issue.
So I would like to set the max length of the payment input field of the POS screen for ex. to 5 at most.
is there a module to do so already ? or
disable barcode event in the pyament screen ?
if no, which function in POS JS files should I modify and can I use JS maxLength() function to do so ?
