Hi there! I understand you're trying to manage a joint BP card account and want to integrate it with the Earnify app. Just to clarify, are you looking to view your husband's BP card transactions or rewards within your Earnify app? Or do you want to link both of your BP cards jointly in one Earnify account?

Getting a bit more detail will help me guide you precisely on how the Earnify app handles joint accounts or multiple card linking. Meanwhile, I can share some general steps on setting up Earnify with BP cards:

1. Download and install the Earnify app if you haven't already.

2. Register or sign in with your phone number or credentials.

3. Add or link your BP card(s) to the app by entering the card details. This lets the app track your fuel and in-store purchases to earn rewards.

Earnify allows you to link credit or debit cards that you use at BP stations, but usually, each card is linked individually for personalized rewards. Since this is a joint account, you might need to add both cards separately under the same app profile if that's allowed.

Could you confirm if your husband also has the Earnify app and if he's linked his BP card there?

Also, are you trying to access just your or his account rewards, or are you looking for a shared view in the app?

Once I get this info, I can walk you through the exact steps to get both cards working smoothly with Earnify.
