Banks take more time in processing checks. For processing checks bank uses special device called reader sorter. This device has ability to scan and print check given by customer. This is why check transactions take more time making customers wait for long duration. Reader sorter uses special ink called MICR toner for scanning check information. This MICR toner has ability to read all ANSI characters. It can clearly sort out minute differences and expose them to bank employees. There are many toners in market, but only few of them follow rules implied by American Bankers Association. Among those who follow these rules HP MICR is on top position. Toners developed by this company come with money back guarantee.
These toners follow strict rules for avoiding fraud transactions. They only print on blank check stock paper. American bankers association imposed strict restrictions on MICR toners. It asked them to set only standard fonts for printing. Those fonts which are used on MICR lines should be perfectly printed at bottom of check. If printer prints check in that format, it will be easy for reader sorter to scan that check. In South America and Israel, American bankers association prescribed CMC-7 as standard font. In other parts of USA it asked banks to use only E-13B font.
