The BDO online app is a separate platform from the physical card, and it allows you to access and manage your account digitally. As long as your online account is active and you remember your login credentials, you can continue to use the BDO online app for various banking transactions, such as checking your account balance, transferring funds, paying bills, and more. However, it's important to note that if you wish to make cash wí†hdráwals from ATMs, you will need to renew your expired ATM card or request a new one from BDO.
