How do you identify travelers checks?

Traveler's checks can be identified by their distinct features, including the issuing bank's name, a pre-printed serial number, and a space for the holder's signature. They typically come in various denominations and have security features like watermarks and color-shifting ink to prevent counterfeiting. Additionally, they often include instructions for how to use them and contact information for reporting theft. Always ensure the checks are intact and have not been altered before use.
