When we opened our doors in San Antonio, Texas over 125 years ago, the West was a wild place, so we made security a high priority. We still do. In fact, just as we did back in the old days, we exceed the industry’s standards for security. Today, Clarke American makes the safest checks you can write.

Our commitment to security is ongoing. Our research and development team is always exploring new technologies. Recently, we’ve added our new patented* printing process system, Enhanced Security Level (ESL™). This system exceeds all existing industry guidelines and requirements. ESL offers the greatest standard protection available.

Get Familiar with Your Check’s Appearance
Clarke American’s patented security printing process is designed to protect you. Familiarize yourself with the security features on your checks. It’s not difficult, and it can make all the difference to the security of your account.

Every check offered on this website includes these security features.

Offering Businesses an Even Higher Level of Protection
Many of our checks have an additional security feature -- the Void Pantograph (VP™) -- which gives businesses an even higher level of protection against counterfeiters. If a check has been photocopied or scanned, the word VOID, which has been invisibly printed in specific locations on the check, will dramatically appear across the face of the copied check.
