OneCard Card Token Deletion: Safety, Impact, and Operational Guide
Card tokenisation is a security mechanism widely used in modern digital payments to protect sensitive card details. In the OneCard credit card app, users can view and delete saved card tokens created for online merchants and applications.
This Knowledge Base article explains what happens when a card token is deleted, whether it is safe, and how it impacts online payments, subscriptions, and card usability, from a technical and operational standpoint.
Technical Explanation
What Is Card Tokenisation?
Card tokenisation replaces the actual credit card number (PAN) with a unique, randomly generated token. This token is:
The real card number is securely stored with the card network (Visa/Mastercard/RuPay), not with the merchant.
How OneCard Uses Tokens
In OneCard:
-
Tokens are created when you save your card on a merchant website/app
-
Each merchant gets a separate token
-
Tokens are governed by RBI card tokenisation guidelines
Deleting a token removes the merchant’s ability to charge your card using stored credentials.
Is It Safe to Delete a Card Token?
Yes. It is technically and financially safe.
Deleting a card token:
-
❌ Does NOT cancel your credit card
-
❌ Does NOT block offline/POS usage
-
❌ Does NOT affect your credit limit or billing cycle
-
✅ Only removes stored access for a specific merchant
What Happens When You Delete a Card Token
Immediate Effects

Saved card payments at that merchant will stop
-
Auto-debit or recurring payments may fail
-
Merchant cannot charge your card without re-authorisation
Unaffected Services

-
Other merchants’ tokens
Common Use Cases

Step-by-Step: Deleting a Card Token in OneCard App
-
Open OneCard App
-
Go to Card Settings / Manage Card
-
Select Saved Tokens / Tokenised Merchants
-
Choose the merchant
-
Tap Delete / Remove Token
-
Confirm the action
The deletion is instant and reversible by re-tokenising later.
Re-Tokenising After Deletion (If Required)
To make payments again on the same merchant:
-
Select payment via credit card
-
Enter full card details
-
Complete OTP / authentication
-
Merchant creates a new token
No additional charges apply.
Commands or Examples (Conceptual)
While tokenisation is handled at network level, conceptually:
Original PAN: 4111-XXXX-XXXX-1234
Token Issued: TKN_9fA8xP23Lm
Merchant Scope: Amazon.in
Deleting the token invalidates TKN_9fA8xP23Lm permanently.
Common Issues & Fixes
Issue 1: Online payment suddenly fails
Cause: Token deleted
Fix: Re-enter card details and re-tokenise
Issue 2: Subscription stopped working
Cause: Auto-debit token removed
Fix: Update payment method with merchant
Issue 3: Card works offline but not online
Cause: No active online token
Fix: Enable online transactions and re-tokenise
Security Considerations
-
Tokens reduce exposure of actual card numbers
-
Deleting unused tokens lowers attack surface
-
Compromised merchants cannot misuse deleted tokens
-
Token deletion is recommended after merchant data breaches
Best Practices
-
Review saved tokens every 3–6 months
-
Delete tokens for inactive merchants
-
Remove tokens before uninstalling apps
-
Keep online transactions disabled when not required
-
Use merchant-specific tokens instead of global saves
Conclusion
Deleting a card token in OneCard is a safe, reversible, and security-positive action. It does not affect your credit card’s core functionality and is recommended when you no longer trust or use a merchant. Token management gives users granular control over where and how their card can be charged.
For uninterrupted services, ensure re-tokenisation is completed where required.
