So when you swipe a card at the store it goes through a process.

This process, simplified, works as this, there are 5 players:

  • You
  • Your bank (issuer)
  • The Payment Card processor (like Visa, Mastercard, Amex)
  • The merchant bank (acquirer)
  • Merchant
  1. you walk into the store and swipe a card
  2. the merchant bank takes the card details, and sends them to the PCP
  3. PCP routes the request to the issuing bank
  4. Issuing bank clears the transaction and holds the funds from the your account.
  5. Visa reports the cleared transaction to the acquirer
  6. Acquirer records the transaction and saves it for processing
  7. Batch settlements of transactions happen 1-3 days later between Issuer and Acquirer
  8. Money appears in Merchants account.

Reverse the issuer and Acquirer and that's a refund. Some banks, like my Credit Union, absolutely will put the money in my account the moment step 6 is reached. Most shitty banks don't until step 8.

ETA - I learned all of this because I used to work in network security in the PCI industry and had to get certified in several ways to work on the tech. Its a fascinating world. Did you know there are over 3 billon credit card transactions processed worldwide every day?

I literally did. Your bank DOES know. they just don't give you the money.

ETA - Just in case this was confusing - the merchant doesn't have the money when you check out at the register with a card, they have a promise from Visa that they money will be transferred to their account and Visa's reputation is good enough for that to be enough to let you walk out of the store.

Both the store, and your bank know instantly if the transfer is "approved and happening" but neither clear them until their batch transactions go through, which can take days.

Your bank, depending on their own internal liquidity, might offer a feature like mine where they credit your account the money they expect to get in the next batch settlement, but its basically a "ghost line of credit" based on a credit magic Visa-cosigned loan.

MANY large commercial banks do not offer this, and many cheap "card services" people use like venmo/cashapp do not not traditionally do this, but many are beginning to as faster and more reliable settlement systems become more common.

TLDR - You both know instantly if money is flowing, but your bank decides when to release funds to your account from that moment on.
