Rosetta Check Intelligence
Research on how checks are printed, protected and cleared
Rosetta Check Intelligence is where Rosetta Technologies publishes what it knows about checks: a market report, a quality checklist, plain-language guides, a book series and an animated series. Everything here is free to read.
Every figure comes from a named source or a published standard.
Reports: free market report
The State of the U.S. Check Market, 2027
9.2 billion checks moved $24.45 trillion in 2024, and the average check is worth nearly three times what it was in 2000. What the federal data shows, and what it means for printing, fraud and clearing through 2027.
Checklists and tools
The MICR quality checklist
Eleven checks a finance or operations team can run on its own check output before the bank runs them. It covers toner, fuser condition, stock, font, and the signal test itself.

- How to read your bank's reject report
- The five failures that cause most rejects
