Introduction
Another way to prevent screenshot abuse is by displaying the barcode security animation, which supports human-verification of a pass.
The physical manifestation of a security animation is a shimmering outline around the barcode of the pass. This shimmering animation triggers only when the device is in motion so one can test the pass’ validity by tilting the device. On the other hand holding the device still will only animate the colorful security animation in loop.
In Google Wallet passes, barcode security animation is a subtle animation effect that adds an extra layer of security to barcodes displayed on your phone.
Note: The security animation feature if only available for Google Wallet passes.
How does security animation work?
It helps prevent unauthorized use by adding a human-verification element that's difficult to replicate with screenshots or static images. Here's how it works:
What it looks like
Imagine a shimmering, rainbow-colored outline around the barcode in your Google Wallet pass. This animated border pulses and shifts as you tilt or move your phone.
The animation only activates when the device is physically moved, ensuring it's not just a pre-recorded video or image.
How it helps
Prevents screenshot abuse: Static barcode images can be easily captured and misused. The dynamic nature of the animation makes it hard to accurately replicate with a screenshot, deterring potential fraudsters.
Human-verification: When presented for redemption or validation, the moving animation confirms the pass is actively displayed on a phone and not a static image, adding a trust factor for merchants or event staff.
Additional layer of security: While not the sole security measure, it complements other features like rotating barcodes (where the barcode itself changes periodically) and NFC technology to enhance overall pass security.
Enabling the barcode security animation
Step 1 - Visit Barcode Tab
Navigate to your pass design, and with the Google Design selected click on the barcodes tab.
Step 2 - Enable Security Animation
Use the toggle to enable Security Animation
Conclusion
Overall, barcode security animation in Google Wallet passes is a subtle but effective way to improve security and prevent unauthorized use. It complements existing features and provides a visual cue for both users and merchants, adding an extra layer of trust and confidence to digital passes.
