# relinkAccount(using:)

Presents a sheet for the merchant to re-accept Tap to Pay on iPhone’s Terms and Conditions on a device using a different Apple Account.

## Declaration

```swift
func relinkAccount(using token: PaymentCardReader.Token) async throws
```

## Parameters

- `token`: The token from your payment service provider. This token contains the merchant identifier and must include permission for relinking.

## Discussion

Discussion To use Tap to Pay on iPhone, your participating payment service provider must provide the merchant using your app with a secure token. This token contains a unique identifier for each merchant and also specifies if relinking using a different Apple Account is allowed. To use this method, a merchant must have already accepted the Terms and Conditions using linkAccount(using:). After a merchant accepts the Terms and Conditions for their specific merchant identifier on one device, they don’t need to accept it again on additional devices that use the same identifier. note: PaymentCardReaderError.accountLinkingFailed, PaymentCardReaderError.accountLinkingCancelled, or other relevant errors in PaymentCardReaderError.
