Separate the one-off purchase from the saved method
Start with the rental confirmation to identify the card used for that completed transaction. Then open Payment method in the Player account to inspect the card currently saved for the account. Those are related observations, but they answer different questions.
A successful rental does not by itself show which card the next recurring payment will use. For example, a card temporarily used for a particular film may have replaced an earlier saved method under the behaviour described by BFI. Record the visible account state instead of relying on who usually pays the subscription.
Choose an update rather than an accidental removal
BFI’s help says a saved card can be removed, but an associated subscription will then expire at the end of the monthly billing period. That makes card removal consequential; it should not be used as a casual way to hide an unfamiliar card while expecting subscription access to continue unchanged.
If the objective is to change the payment method, use the current account controls for that purpose and check the resulting saved method. If the objective is to end renewal, review the subscription’s own status and end date as well. Keep those objectives clear before making a payment-account change.
Keep the evidence needed for an unexpected charge
For a later billing question, retain the rental receipt, the subscription renewal context and the last digits shown for the saved card. Do not email full card numbers or security codes. Explain whether you are querying the completed rental, the saved method or a subsequent renewal.
This behaviour is described for the direct BFI Player account. A channel subscription managed by another platform should be checked in that platform’s own billing account. Resolving the payment record first is more useful than reinstalling a television application, since a playback app is not the evidence for which payment method was stored after a website rental.

No. The help says the associated subscription will expire at the end of the monthly billing period.
