This conversion kit lets you convert your existing printer into a bank compliant check printer with a Magnetic Ink Character Recognition (MICR) black ink cartridge, VersaCheck Gold check software, 150 starter check forms and deposit slips, and a handheld GoTest MICR Scanner. Setup is super easy – simply remove your existing black ink cartridge and snap in the included VersaInk MICR Black ink cartridge to make your printer instantly bank compliant. VersaInk MICR Black cartridges are equally able to handle all your everyday document printing, copying, and scanning. Easy-to-use, the included VersaCheck software lets you print checks directly from VersaCheck or from within your QuickBooks, Quicken or other accounting software. VersaCheck saves you 50-80% or more vs. buying checks from banks and mail-order suppliers. Also included is the GoTest 3-in-1 authenticity detector for checks and documents. The GoTest will activate magnetic ink, scan magnetic ink and reveal invisible UV ink.
