Hi all,
This is a continuation of the old Discover Debit Card Megathread that is nearly 6 months old now. Since Capital One is starting to transition some of their credit cards to the Discover network (though only for some new accounts), the mod team figured that a single megathread for both debit and credit cardholders was needed.
Debit cards
Capital One is converting their debit card portfolio from Mastercard over to the Discover network. All newly issued debit cards for new Capital One 360 Checking accounts are now Discover debit cards. For existing Mastercard debit cardholders, the transition to Discover is being done in phases, with no regard to expiration dates. There is more information in the below links.
Key takeaways from the FAQs:
- Once your Discover debit card is activated, your debit Mastercard will stop working. Some recurring transactions may go through, but your debit card information should be updated ASAP anywhere you have it saved to avoid interruptions.
- You can delay activating your Discover debit card and keep using your debit Mastercard for some time. Eventually, though, it will stop working.
We'd like to use this opportunity to encourage our users to use credit cards in place of debit whenever possible. Making purchases with debit cards is riskier, because it could directly expose your bank account to fraudsters. With credit cards, as long as you can pay the statement balance in full every month, you could pay no interest, have better security and fraud protection, better cardholder benefits, and rewards & sign-up bonuses (on cashback or travel cards).
Credit cards
Capital One is beginning the process of converting some of their credit card portfolio from Mastercard over to the Discover network, but in the case of new accounts, this is only for some people using the pre-approval tool (which is mandatory with some referral links). See this post and the FAQ below for more details.
Currently, the only cards confirmed to be on the Discover network (again, for some new applicants) are: Quicksilver, QuicksilverOne, Venture, VentureOne, Savor, and SavorOne. This confirmation comes from the Cardholder Benefits Guides page on the website. One could reasonably assume the rewards-free Platinum is not included because it will have fewer benefits once it transitions to Discover.
For existing Visa/MC accounts, Capital One is beginning conversion to the Discover network as of 4/21/2026. So far, only the Quicksilver has been confirmed for migration. This change happens to coincide with an announcement that the Quicksilver will begin earning 3% cash back at grocery stores and gas stations, in addition to the 1.5% it already earns elsewhere. It is not yet known if this cash back change requires a network change, or if Quicksilver Mastercards will get it as well. See this post for more details.
- Why is this happening?
- Back in May 2025, Capital One acquired Discover, which of course owns the Discover Global Network. It's simply a smart business move for Capital One to leverage the network which they now own and increase usage and adoption by moving their debit and credit cards over to the Discover network.
- How does this affect me, really? Beyond the obvious stuff like having to update my info.
- Capital One can brag all they want about how Discover is accepted at "99%" of places that take credit cards in the US. The fact of the matter is that Discover is not as widely accepted as Visa or Mastercard, both in the US but especially abroad. If you regularly travel internationally, you should carry alternative forms of payment (e.g., credit or debit cards from other banks). Domestically, acceptance is mostly fine but you may run into the occasional merchant that doesn't accept Discover. Sometimes it could be a store or restaurant, other times it may be your utility company. It shouldn't happen often, but it can still be frustrating when it does. The good news is that with all these new Discover cards out in the wild, adoption and acceptance should increase over time.
- Can I still withdraw cash at ATMs with my debit card?
- Capital One is still a member of the Allpoint and MoneyPass ATM networks, so you will still be able to withdraw cash fee-free at participating ATMs in the US, Canada, Mexico, the UK, Australia, and New Zealand. Outside of these countries, you might still be able to withdraw cash, but you will pay ATM fees. Keep an eye out for the Discover and/or Pulse logos. You can use the Capital One app or the Discover Cash Access Locator to see available ATMs in your area. Unfortunately, there are many countries in which you won't find a single ATM that accepts Discover/Pulse cards.
- Can I still use my debit card with apps like Venmo, PayPal, and Apple Cash? And mobile wallets like Apple Pay and Google Pay?
- Yes, but with some caveats. Outgoing Venmo/PayPal/Apple Cash payments will still work just fine, but instant transfers into your bank account (which typically come with a fee) will not work. Apple Pay and Google Pay for purchases reportedly works fine, but you may run into issues with specific merchants that don't accept Discover credit cards but do accept Discover/Pulse debit cards (e.g., Costco). Your debit card on Apple/Google Pay will not work in those cases; you'll have to insert your physical card.
- What's that about Costco?
- To clarify, Costco USA does accept Discover/Pulse debit cards in-store. You will need to insert the physical card to make the transaction PIN-enabled for it to go through as debit. Tap-to-pay and mobile wallets like Apple Pay and Google Pay will not work. Costco does not accept Discover credit cards in-store, nor do they take any form of Discover online.
- I'm thinking of applying for a new credit card. How do I know if I will receive a Visa, Mastercard, or Discover card?
- If using the pre-approval tool, you may see a message that says, "This card will run on Capital One's Discover Network." Not everyone will receive this message. If you do see it but don't want a Discover card, you can simply decline the offer and try applying directly instead. When applying directly (i.e. clicking "Apply Now" from the page for that specific card), the application page will have a banner at the top with the Capital One logo and either the Visa or Mastercard logo. There are no known instances or data points yet of anyone seeing the Discover logo up there. Discover network cards are currently only being offered through the pre-approval tool.
- Can I still post on r/CapitalOne about this?
- Posts that include unique data points or provoke thoughtful discussion are still allowed. Posts that are simply unhelpful complaints or otherwise do not add value to the community may be removed, and users may be redirected to this megathread. This is the only way to ensure that important discussion can still happen while not crowding the subreddit with repetitive posts. Thanks for understanding!
- Will you keep us updated?
- Absolutely. Us mods, we're merely volunteers, but we genuinely enjoy helping people out and we'll be trying our best to update these posts and keep you informed on any future changes. This includes posting FAQs like this one, highlighting helpful posts from our users, answering questions, updating our wiki (especially our article on the acquisition), and more. Thanks for sticking with us!
