The company does not usually lend to cardholders. That matters because Visa avoids the balance-sheet credit risk that banks carry while still earning fees when transactions flow across its network. The more credentials, merchants, issuers, acquirers, wallets, and platforms connected to Visa, the stronger the network becomes.

Block Inc competitive advantage: Block's advantage is the combination of Square's seller workflow, Cash App's consumer network, Afterpay's commerce relationships, and product design speed.
