Apple pay

They will not be able to view your Transactions that you make with your physical card. The only transactions that will show will be the ones that are made within the Wallet App using Apple Pay or Apple Cash.

Welcome to Apple Support Community!

You are not able to remove it from their wallet without their device. You will need to ask them to remove it themselves.

Change or remove the payment methods you use with Apple Pay: https://support.apple.com/en-us/HT205583

Hope this helps ;)

Cancel the Card:

You can't log into the account. So, cancel your credit card, and get a new one, ASAP.

Modify your Credentials:

Having so much suspicion, consider modifying your credentials, ASAP, starting with a new password.

• Modify: your login credentials (using both a New eMail and a New Password) for Apple and each and all sites
• Associate: a different method of payment to your account
• Enable: Two-Factor Authentication for Apple ID PayPal and for all other accounts that have such an applicable option

Why would you give someone else your card? But, yes. If it was added to their wallet, they can use it freely. Of course, in order to add it they would also need to pass the authentication process, which generally means logging into your credit card's site.

Cancel the card.
