Lock card prebuilt component

The lock card prebuilt component authenticates the user, retrieves cards registered to the user, and allows the user to lock a card temporarily, lock a card permanently, or reactivate a card. After confirming a locked card, the component allows the user to request a new card. This component uses a customized version of the Authentication prebuilt component to authenticate cardholders.

Limitations

In addition to the common prebuilt component limitations, this prebuilt component has the following limitations:

  • This component does not encrypt any data.

Sample dialogs

The following sample dialogs demonstrate common scenarios handled by this prebuilt component. The sample dialogs demonstrate behavior when the component is called via telephony, which triggers the Default Welcome Intent and the first agent response at the start of the conversation.

Unauthenticated user with multiple cards

The agent identifies that the user has not been previously authenticated and collects information to verify that the user is a registered cardholder. Once the user has authenticated, the agent retrieves information about the cards registered to the user. The user confirms they would like to temporarily lock a selected card, and the agent generates the lock card request.

User input Agent response
Agent authenticates user using Authentication prebuilt component
Thank you, you have been successfully authenticated.
Please wait while we are fetching your card details.

We have found multiple cards registered with your number. We have a Visa ending in 5555, a Visa ending in 6666, a MasterCard ending in 4444, and a MasterCard ending in 4449.

Please tell us the last 4 digits of the card you would like to lock or reactivate.
4444
The last four digits of the card number that we got is 4444, is that correct?
Yes
Do you want to lock your card temporarily or permanently?
I want to lock it temporarily
Please tell us why you are locking your card. You can choose from options like damaged, stolen, lost or others.
It got damaged
Sorry to hear that. For security purposes, we need to validate your identity, so we will send you a code. Do you prefer to receive the code by phone or by email?
Send it to my phone
Okay, before proceeding, we will send a code to your registered mobile number. Can you please confirm your code to validate the request?
123456
Okay, your card ending with 4444 will be temporarily locked. Once locked, you will not be able to make any transactions online or on POS machines with that card. Do you confirm this action?
Yes
Your card was locked successfully. Your request number is 9711485 and has been shared successfully with your registered mobile number.

Authenticated user with single card

The agent identifies that the user has been previously authenticated and retrieves information about the card registered to the user. The user selects to permanently lock the card, and the agent generates the permanently lock card request. The agent then asks the user whether they would like to reissue a new card for the permanently locked card, and creates a reissue request for the card.

User input Agent response
Please wait while we are fetching your card details.

We have found your MasterCard ending in 4444. Do you want to lock your card temporarily or permanently?
Permanently
Please tell us why you are locking your card. You can choose from options like damaged, stolen, lost or others.
It was damaged
Sorry to hear that. Don't worry, we will permanently lock your card. Can you please confirm if the card ends with 4444?
Yes
Okay, before proceeding, we will send a code to your registered mobile number. Can you please confirm your code to validate the request?
123456
Okay, your card ending with 4444 will be temporarily locked. Once locked, you will not be able to make any transactions online or on POS machines with that card. Do you confirm this action?
Yes
Your card was locked successfully. Your request number is 6108410 and has been shared successfully with your registered mobile number.

Do you want to reissue a new card?
Yes
We will deliver the card to your registered address. Can you please confirm your delivery address zip code 12345?
That's correct
Okay, please wait for a few seconds while we are raising the request for reissuing a new card.

The reissue request for the new card was successful. Your request number is 3808109 and has been shared successfully with your registered mobile number.

The card will be delivered to your registered address in 3 working days. To use the card please follow the instructions shared with the card.

Reactivate card

The agent identifies that the user requires additional authentication and sends a one-time password to verify the user's identity. The user requests to reactivate a card, and the agent transfers them to a human agent to continue.

User input Agent response
For security purposes, we need to validate your identity, so we will send you a code. Do you prefer to receive the code by phone?
Yes
We have sent a code to your registered phone number ending with 5041. This may take a few seconds. Can you please confirm the code?
