Why I Use Pen To Write Checks To Prevent Washing

I always make it a point to use a pen when writing checks because it adds a layer of security that I can trust. When I write with a pen, especially one with permanent ink, it becomes much harder for anyone to alter the information on the check. If someone tried to wash the ink off or change the numbers, the marks would smudge or leave obvious traces, making tampering evident. This simple step gives me peace of mind knowing my money is safer.

From my experience, using a pen also helps in maintaining the integrity of the check. Pencil or erasable ink can easily be modified, increasing the risk of fraud. By committing the details in pen, I’m protecting myself from potential financial loss and the hassle of disputing fraudulent transactions. It’s a small habit that makes a big difference in keeping my finances secure.

My Buying Guides on Pen To Write Checks To Prevent Washing

When it comes to writing checks, one of my biggest concerns has always been preventing check washing—a type of fraud where someone erases the ink to alter the check details. Over time, I’ve learned that choosing the right pen can make a significant difference in protecting my checks. Here’s my personal guide on what to look for when buying a pen specifically to write checks and prevent washing.

Why Choosing the Right Pen Matters

From my experience, not all pens are created equal when it comes to security. The ink must be resistant to chemicals and solvents that fraudsters use to wash checks. If the ink fades or can be removed easily, it leaves your financial information vulnerable. So, picking a pen with the right ink type is the first and most important step.

Ink Types to Look For

I always look for these ink types because they offer the best protection:

  • Gel Ink: Gel pens use pigment-based ink that tends to be water-resistant and less prone to smudging or fading.
  • Permanent or Archival Ink: These inks are designed to be long-lasting and resistant to solvents. Some brands specifically mention “wash-proof” or “archival” qualities.
  • Pigment-Based Ink: Unlike dye-based inks, pigment inks are more stable and harder to remove with chemicals.

Pen Tip Size and Comfort

While security is my top priority, I also consider how comfortable the pen is to write with. A pen with a medium tip (around 0.7mm to 1.0mm) gives me clean, clear lines without bleeding through the paper. If the tip is too fine, the ink might be less saturated, making it easier to alter. Too broad, and it can look messy.

Durability and Ink Flow

I want a pen that writes smoothly without skipping because incomplete or faint lines might raise suspicion or be easier to tamper with. A consistent ink flow ensures my checks look professional and are harder to alter.

Brands I Trust

Based on my experience and research, here are some brands that stand out for writing checks securely:

  • Uni-Ball Vision Elite: Their ink is water-, fade-, and fraud-resistant.
  • Pilot Precise V5 RT: Known for its archival-quality ink that resists washing.
  • Sharpie Pen: Not the marker, but the pen version uses permanent ink that dries quickly and resists smudging and washing.

Additional Tips I Follow

  • Always write with a fresh pen that has good ink saturation.
  • Avoid using erasable pens or pencil-like pens for checks.
  • Store your checks securely to prevent physical tampering.
  • Consider using security features on checks themselves, like microprinting or watermarks, in addition to secure ink.

Final Thoughts

Choosing the right pen has been a simple yet effective way I protect my checks from fraud. By focusing on ink quality, pen comfort, and trusted brands, I feel confident that my financial documents are much safer. If you’re looking for a reliable pen to write checks and prevent washing, keep these points in mind, and you’ll find one that fits your needs perfectly.
