Auto-fill CVCs during checkout

Problem Context

Users rely on virtual cards for secure online payments without carrying physical cards. Recently, services like Walmart OnePay now require entering the CVC code every checkout, breaking the one-click workflow. This forces users to manually log in to retrieve the CVC, slowing down purchases and creating security risks if they write it down.

Pain Points

The main pain points are: (1. Lost efficiency—what was a one-click checkout now requires multiple steps, (2. Security risks—users resort to sticky notes or screenshots, exposing sensitive card details, and (3) Frustration—navigating virtual card apps mid-checkout is clunky and disrupts the flow. Manual workarounds fail because they either slow you down or compromise security.

Impact

The impact is significant: users waste *5+ minutes per order- dealing with CVC entry, risk fraud from exposed card details, and may abandon virtual cards entirely, losing the convenience they signed up for. For frequent shoppers, this adds up to hours of wasted time per month and potential financial losses from security lapses or missed deals.

Urgency

This problem is urgent because it *happens every single checkout- for affected users. If ignored, they’ll either switch back to physical cards (losing security benefits) or give up on the service entirely. The risk of *exposed CVCs- also grows with every manual note taken, making it a daily security and convenience crisis.

Target Audience

Beyond Walmart OnePay users, this affects anyone using virtual cards from services like Amazon, Revolut, Capital One, or bank-issued virtual cards. Frequent online shoppers, subscription service users, and small businesses paying vendors are all impacted. Even power users who rely on password managers don’t have a solution for CVC auto-fill in checkout forms.

Solution Approach

AutoCVC is a *browser extension- that securely stores your virtual card’s CVC and auto-fills it during checkout—just like a password manager, but for payment security. It eliminates the need to log in to your virtual card app mid-purchase, restoring the one-click checkout experience while keeping your CVC safe. The extension works across all e-commerce sites and virtual card providers.

Key Features

1. Secure Local Storage: Encrypts your CVC on your device (no cloud sync) and requires your master password to access.
2. Multi-Card Support: Stores CVCs for all your virtual cards in one place.
3. No Login Needed: Works silently in the background—no extra tabs or app switches required during checkout.

User Experience

When you start checkout, AutoCVC *automatically detects the CVC field- and fills it in—no clicking, no logging in. If you have multiple virtual cards, it prompts you to select the right one (e.g., ‘Use Walmart OnePay?’). The CVC is stored only on your device, so you control access. It feels like magic: your checkout flows as fast as before, but now with security.

Differentiation

Unlike password managers (which don’t handle CVCs) or virtual card apps (which require manual logins), AutoCVC is the *only tool- designed specifically for this problem. It’s faster than sticky notes, more secure than writing it down, and works where native solutions fail. The local encryption ensures no third party ever sees your CVC, unlike cloud-based tools.

Scalability

The product scales by adding support for *more virtual card providers- (e.g., Revolut, Amazon) and *integrations- (e.g., password managers, browser autofill). A premium tier could offer *multi-device sync- (encrypted) or advanced security alerts (e.g., ‘This site looks suspicious—confirm CVC entry?’). As users add more virtual cards, they’ll see more value in the subscription.

Expected Impact

Users save 5+ minutes per order, eliminate security risks from manual notes, and restore their one-click checkout workflow. For businesses, it reduces cart abandonment and fraud risks. The peace of mind from *never typing your CVC manually again- makes it a must-have for power users. Over time, the product can expand to include *payment security audits- or *fraud detection- for even higher value.
