Checks may be an established way to pay vendors, employees and other business expenses, but they remain a common target for fraud. Criminals can wash checks, alter payee names or amounts, create counterfeits or steal blank checks and use them without authorization. Simply ordering checks from a legitimate supplier doesn’t necessarily protect you. The check stock itself should have features that make tampering and copying more difficult.
How can you ensure your business checks are secure from fraud? RELYCO, which specializes in high-security business check stock and has over 35 years of experience, offers several useful considerations when evaluating your options.
1. Start With Checks Designed for Fraud Prevention
The first step is to choose a check stock specifically designed to deter fraud, rather than treating security as an afterthought. This is important because checks remain among the most frequently targeted payment methods by criminals.Â
According to the Association for Financial Professionals’ 2026 Payments Fraud and Control Survey, 58% of organizations reported check fraud in 2025, making checks more frequently affected by fraud than ACH and wire payments. The risks can take several forms, including:
- Check washing, where information is chemically removed and rewritten.
- Altered payee names or amounts on legitimate checks.
- Counterfeit checks created from copied or reproduced documents.
- Internal theft, including unauthorized access to blank check stock.
- Copying and scanning, which can be used to reproduce checks.
High-security check stock can make these methods more difficult and, in some cases, make attempts at alteration easier to detect.
2. Know Which Security Features to Look For
Look for multiple layers of protection, since visible elements can discourage criminals, while hidden or reactive ones can help expose attempts to alter or reproduce a check.Â
RELYCO explains, “Visible security features are an effective way to deter criminals, and each additional feature makes your check more secure.”Â
Depending on the check stock, useful features can include watermarks and simulated watermarks, microprinting, copy-void pantographs and covert fluorescent fibers. Thermochromic heat-reactive ink, solvent-reactive features, enhanced toner adhesion and security backgrounds are also good attributes.
Having more than one security feature is important because different security features address various methods of fraud. For example, a watermark can help authenticate the paper, while a copy-void feature can make a reproduced check visibly different from the original.
3. Check Tamper Resistance Features
A legitimate check can still become fraudulent after it leaves your business. Someone may attempt to remove information, change an amount or alter the document before presenting it for payment. That makes tamper resistance just as vital as preventing counterfeit checks.
Find features that can help reveal chemical alteration, physical manipulation, splicing, copying or scanning. Solvent-reactive color spotting can help expose chemical attempts to alter the check, while anti-splice backers can make physical modification more difficult. Copy-void features and enhanced toner adhesion can add further protection against reproduction and manipulation.
RELYCO specifically recommends high-security check stock with dual-tone true watermarks, toner anchorage and thermochromatic ink. According to the company, these features are intended to prevent common methods of alteration, such as chemical washing and photocopying.
4. Make Sure Your Checks Meet Current Standards
Security is only useful if your checks can be processed properly by the banking systems that handle them. Before ordering, confirm that your supplier keeps its check stock aligned with relevant industry standards. One criterion to look for is the ASC X9AB Check Processing Committee-approved standard, which covers check processing. RELYCO says its business and custom check stock is updated to comply with ASC X9AB-approved standards.
You should still confirm the requirements that apply to your bank and account before ordering. Don’t assume that every type of check stock will work with your particular setup simply because it is marketed as secure.
5. Choose a Supplier You Can Rely On
Your supplier is part of your security strategy. When comparing options, consider whether the business clearly explains its safety specifications and keeps its products up to date. Here’s what you need to check:Â
- Clearly documented security features
- Information about applicable standards
- Consistent product specifications
- Options compatible with your banking setup
- Straightforward ordering and customer support
A supplier should be able to explain what makes its checks secure, rather than simply describing them as “fraud-resistant.” This gives you a clearer basis for comparing products and choosing the right level of protection for your business.
6. Consider Customization Without Sacrificing Security
Your business may need checks customized with its branding, account information, layouts or other operational details. That doesn’t mean security features need to take a back seat. For example, security-focused options can include image-friendly amount boxes, voidless postal windows and nonnegotiable stub backers. These features can help a check work smoothly within your payment process while adding another layer of protection.
RELYCO notes, “Fraudsters will stop at nothing to uncover payment methods with the weakest controls.” In other words, customization should support your workflow without creating unnecessary weaknesses in the check itself.
7. Make Secure Checks Easy to Order and Use
Security measures are easier to maintain when they fit naturally into your payment process. If ordering replacement checks is complicated or the available options are unclear, you may be tempted to settle for a less secure alternative.
That’s why it’s important to work with a supplier that provides clear product specifications, straightforward ordering, suitable layouts and consistent availability. You should also be able to understand which security features you are getting before you place an order.
Frequently Asked Questions
Below are some of the most common questions about security features for business checks.
What are the most important security features for business checks?
Look for several security measures working together, including watermarks, microprinting, copy-void features, chemical-reactive safeguards and other anti-tampering features. According to RELYCO, each additional security feature can make a business check more difficult for criminals to copy or alter.
What are the best secure checks for small businesses?
The best option depends on your payment process and banking requirements. However, it’s best to choose check stock with multiple security features, current processing standards and a reliable supplier. Don’t make price your only deciding factor when the cost of fraud can be much greater.
How can you protect business checks from internal theft?
Keep blank checks in a secure location and limit access to authorized employees. Track check numbers, reconcile your bank account regularly and investigate unfamiliar transactions promptly. These controls work alongside security features built into the check stock.
Give Fraud a Reality Check
Securing your business checks starts with choosing check stock that does more than carry your payment information. Make sure there are multiple layers of fraud prevention and tamper resistance, confirm that the checks meet relevant processing standards and choose a supplier that can clearly explain its security features.
