Why use MICR in Laser Check Printing?

Computer generating checks with laser printers offers many advantages for businesses that manage multiple bank accounts:

• Avoids the expense and time delay of purchasing pre-encoded check stock.
• Eliminates potential for waste when a bank account is changed or closed.
• Increases security since only non-negotiable blank check paper is stored. 
• Speeds check processing by reducing the need to change check stock for each account and by using high speed laser printers. 
• Allows for easy incorporation of signatures and/or logos during check processing.
• Permits checks to be printed at remote locations.
