# Review card LCM

### Overview

Using the D1 backend API, the issuer can [suspend](/nfc-payment/integrate-the-d1-api/d1-api-reference/inbound-api-to-d1/card-api.md#post-v2-issuers-issuerid-cards-cardid-operations-suspend), [resume](/nfc-payment/integrate-the-d1-api/d1-api-reference/inbound-api-to-d1/card-api.md#post-v2-issuers-issuerid-cards-cardid-operations-resume), and [delete](/nfc-payment/integrate-the-d1-api/d1-api-reference/inbound-api-to-d1/card-api.md#post-v2-issuers-issuerid-cards-cardid-operations-delete) cards:

* Card suspension or resumption has no effect on NFC Payment digital cards.

  For example, the end user can still pay with a digital card even if the physical card is suspended because it was lost.
* Card deletion deletes all the related digital cards in NFC Payment.

The next section explains how to handle card renewal.

### Card renewal

Cards can be renewed when they expire or replaced if they are lost or stolen.

To display the correct card metadata, the issuer backend must send a [renew](https://thales-dis-dbp.stoplight.io/docs/d1-api-public/0faa18fed5b85-renew) or [replace](/nfc-payment/integrate-the-d1-api/d1-api-reference/inbound-api-to-d1/card-api.md#post-v2-issuers-issuerid-cards-cardid-operations-replace) request to D1. If the request does not include encrypted card details, D1 calls the issuer backend through the [Get Card Credentials](/nfc-payment/integrate-the-d1-api/d1-api-reference/outbound-api-from-d1/card-api.md#get-cms-api-v1-issuers-issuerid-cards-cardid-credentials) API to retrieve the new card details.

If the renew operation updates the card ID, the issuer application should call one of the following APIs after it receives a [`PushResponseKey.TYPE_CARD_RENEWAL`](https://thales-dis-dbp.stoplight.io/docs/d1-developer-portal/tx0ctsp29oo0v) message:

* `D1PayWallet.getDigitalCardList`
* `D1PayWallet.getDigitalCard`
* `D1PayWallet.getCardDigitizationState`

{% hint style="info" %}
Call `D1Task.login` before you call any of the APIs listed above.
{% endhint %}

In the background, card ID resynchronization starts automatically when all of the following conditions are met:

* The end user is logged in.
* The card renewal process completed successfully.
* There is no ongoing contactless payment.
* There is at least one digital card in the wallet.
* The card renewal happened after the last resynchronization.
* The last resynchronization happened more than 30 minutes ago.

If any of these conditions is not met, card ID resynchronization is skipped.

If `D1PayWallet.getDigitalCard` or `D1PayWallet.getCardDigitizationState` is called with the old card ID after a successful card ID resynchronization, the API may return `D1Exception.ErrorCode.ERROR_CARD_NOT_FOUND`.
