I&#x27;ve noticed a trend to prevent copying and pasting into HTML fields which I find quite irrational.  Doesn&#x27;t accuracy increase if I&#x27;m allowed to copy and paste something?  Presently, I&#x27;m prevented from copying a checking account number into a field, so I have to type it out by hand, which is much more error-prone.  Does anyone know why sites do this?
