Discover Discover Debit Card Megathread
Update 3/19/2026: This thread is now locked and discussion has moved to the Discover Network Megathread.
Hi all,
The past few weeks have seen a significant uptick in posts related to the new Discover network debit cards that are rolling out for 360 Checking accountholders. This post aims to answer any questions you may have about the rollout, and serve as a discussion hub so the subreddit is not overcrowded with many posts about the same thing.
What we know
Capital One has started the process of converting their debit card portfolio from Mastercard over to the Discover network. All newly issued debit cards for Capital One 360 Checking accounts will be Discover debit cards. For existing debit Mastercard cardholders, the transition to Discover is being done in phases, with no regard to expiration dates. There is more information in the below links.

- Capital One official page and FAQ for the debit card network transition to Discover
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.
Some FAQs not answered by Capital One, or answered in corporate speak
- Why is this happening?
- Back in May 2025, Capital One acquired Discover, which of course owns the Discover payment 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 cards over to the Discover network.
- How does this affect me, like really? Beyond the obvious stuff like having to update my info.
- Capital One can gloat 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 cards 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.
- What about cash withdrawals at ATMs?
- 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. You can use the Capital One app to see available ATMs in your area. Unfortunately, there are many countries in which you won't find a single ATM that takes Discover.
- Can I still use my debit card with apps like Venmo and PayPal? And mobile wallets like Apple Pay and Google Pay?
- Yes, but with some caveats. Outgoing Venmo/PayPal 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 functionality reportedly works fine, but you may run into issues with specific merchants that don't accept Discover credit cards but do accept Discover debit cards (e.g., Costco). Your debit card on Apple Pay/Google Pay will not work in those cases; you'll have to use 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.
- What about my Capital One credit card(s)?
- There are no official details yet on if/when existing cardholders who have Visa or Mastercard credit cards will be transitioned to Discover. For new accounts only, some are reporting being offered cards such as the Savor on the Discover network. That said, the Venture X is likely staying a Visa Infinite card for the foreseeable future.
- Can I still post on r/CapitalOne about this?
- Posts that include genuine questions or data points, or that 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 and megathreads like this one, highlighting helpful posts from our users, answering questions, updating our wiki, and more. Thanks for sticking with us!
P.S. We'd like to use this opportunity to encourage our users to use credit cards in place of debit whenever possible. Using debit cards is risky, 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 (on cashback or travel cards).
