Register for Online Banking
Check the sticker on the card for the bank's website. Most banks that offer online card activation require customers to register for online banking before they can activate their debit cards. The registration process involves supplying identifying information such as your account number, Social Security number and any other information that the bank can verify from its records. You might find the link to begin the process on your bank's homepage. Follow the instructions to complete your registration.
Log in to your account and locate the link to activate your debit card. The information required depends on the bank but typically includes your first and last name, the card number, the expiration date and the three-digit code on the back of the card. If your bank has sent you a PIN, enter it in the appropriate box when prompted. If not, create your own. Click the submit button when you have entered the required details. Sign the strip on the back of your card once it is activated.
The process for activating a prepaid debit card is somewhat different from that of bank debit cards. For instance, not all providers require card owners to enroll for online access. When you arrive at PayPal's Prepaid MasterCard or NetSpend's prepaid debit card activation pages, you can begin to enter the information necessary to activate the card. Also, most require just the card number and the security code, and you can create your own PIN. Check the back of the card for the provider's website.
Activating Your Card Safely
Online activation is convenient, but a hacker could capture your card number and bank account information if you don't take some safety measures. For instance, go online with a secure Internet connection, such as a wired connection or a wireless connection encrypted with WPA or WPA2 protocols. Don't activate your card on a public computer. Ensure you have correctly typed in the card provider's website address so you don't end up at a phishing website designed to record your financial details. Also, once you are at the right website, look for a lock on the address bar before you enter sensitive information. The lock indicates a secure website.
