There are two distinct layers in the credit card industry: issuers (the banks that give you the card) and networks (the payment rails that process transactions). Understanding the difference helps you choose the right card for your needs.
Credit Card Issuers vs. Networks
| Layer | Who They Are | Role |
|---|---|---|
| Issuer | Chase, Capital One, Citi, Bank of America, US Bank | Lends you money, sets your rate and limit, handles rewards |
| Network | Visa, Mastercard, Amex, Discover | Processes payment between merchant’s bank and your issuer |
Most cards combine an issuer with a network: a Chase Sapphire Reserve is issued by Chase and runs on the Visa network.
The Four Credit Card Networks
Visa
The world’s largest payment network by transaction volume. Visa itself issues no cards — it only provides the payment infrastructure. Virtually every major bank issues Visa-branded cards.
- Accepted at ~100 million merchants in 200+ countries
- Two tiers in the US: Visa Traditional and Visa Signature/Infinite (premium benefits)
Mastercard
Similar global reach to Visa. Like Visa, Mastercard does not issue cards — it provides the network. Competes directly with Visa for bank partnerships.
- Accepted at nearly the same merchant footprint as Visa
- Tiers: Standard, World, World Elite Mastercard (premium)
American Express (Amex)
Unique as both a major issuer and a network. Amex issues its own cards (Gold, Platinum, Blue Cash, Green) and also licenses its network to a few other banks. Historically associated with premium travel rewards.
- Accepted at ~10.6 million US locations (slightly less than Visa/Mastercard)
- Known for premium perks: airport lounges, travel credits, purchase protections
Discover
Also both a network and an issuer for all its own cards. Known for the Discover it line (flat cashback, no annual fee). Acceptance has grown significantly and now rivals Amex in the US.
- Accepted at ~10.5 million US locations
- No foreign transaction fees on most Discover cards

Store Cards and Co-Branded Cards
Many retailers partner with issuers to offer co-branded cards:
- Amazon → issued by Chase (Visa network) or Synchrony (closed-loop store card)
- Delta SkyMiles → issued by American Express
- Southwest Rapid Rewards → issued by Chase (Visa)
- Apple Card → issued by Goldman Sachs (Mastercard network)
- Target RedCard → issued by TD Bank (Visa) or as a closed-loop debit card
Co-branded cards earn rewards in a partner’s loyalty currency (miles, points) rather than straight cash back.
Choosing the Right Card Company
- Best acceptance worldwide: Visa or Mastercard (nearly identical)
- Best premium travel perks: American Express
- Best no-annual-fee cash back: Discover or Citi
