The redesigned $100 bill introduced advanced security features to reduce counterfeiting and streamline cash handling. This update reflects ongoing efforts by currency authorities to balance durability, usability, and anti-fraud technology in everyday banknotes.
Circulated since 2013, the new $100 bill combines color-shifting ink, a 3D security ribbon, and watermarks to improve authenticity verification. Understanding these changes helps businesses, collectors, and the public recognize genuine notes quickly.
| Feature | Location | How to Verify | Purpose |
|---|---|---|---|
| 3D Security Ribbon | Embedded in the center | Tilt the note; bell and stars move | Hard to reproduce with traditional printing |

| Microprinting | Along collar and scroll borders | Use magnifier; text remains sharp | Prevents scanning and photocopy fraud |
| Security Thread | Vertical strip on right | UV light shows “USA 100” | Retail and bank machine detection |
Security Features on the New $100 Bill
The upgraded security suite on the $100 note responds to evolving counterfeiting techniques. Each element targets specific fraud risks while remaining accessible to cash handlers and automated systems.
3D Security Ribbon and Bell in the Inkwell
The embedded security ribbon and color-shifting inkwell create dynamic visual cues. Merchants and bank tellers can confirm authenticity by tilting the note, without special equipment in many cases.
Watermark and Security Thread
The right-side watermark and embedded thread provide fast checks for high-volume environments. Ultraviolet features add a second verification layer for financial institutions.
Design and Historical Elements
The updated $100 design preserves recognizable imagery while integrating modern motifs. These choices honor legacy figures and communicate stability in everyday commerce.
Portrait and Serial Numbers
Benjamin Franklin remains the focal point, framed by finely detailed borders. Subtle gradients and precise alignment make each note visually consistent yet distinct.
Backdrop and Fine-Line Engraving
Independence Hall anchors the reverse, rendered with enhanced detail. Fine-line engraving produces tactile depth that resists basic reproduction methods.
Impact on Commerce and Accessibility
Point-of-sale systems and ATMs were calibrated to accept the new $100 format with minimal disruption. Clear guidelines help retailers and banks transition inventories smoothly.
Handling and Durability
The polymer-infused cotton blend improves resistance to wear, extending the note’s life in circulation. Standard sorting and authentication equipment recognize updated patterns without hardware changes.
Global Context and Comparisons
Many major economies have modernized banknotes with similar multilayer security. The $100 update positions U.S. currency alongside international standards for durability and anti-counterfeiting.
International Adoption Trends
Central banks worldwide prioritize features like color-shifting ink, transparent windows, and tactile marks. These shared strategies raise the production barrier for counterfeiters globally.
