If you are looking for information about https://safewallet.us/como-funcionan-los-comercios-y-las-tarjetas-de-credito, this guide explains how credit cards actually work and their relationship with businesses, using simple language but with enough depth for those who want to understand the modern financial system.
Every time you pay with a credit card, a process takes place that lasts only a few seconds but involves banks, payment networks, security systems, and merchants. Although the procedure seems simple to the consumer, behind it lies a financial infrastructure designed to verify the buyer’s identity, authorize the transaction, and ensure that the money reaches the seller.
What happens when you pay with a credit card?
When you tap, insert, or swipe a card, you’re not immediately transferring money from your account. The issuing bank is actually lending that money temporarily to the cardholder.
The basic process is:
| Passed | What happens |
| 1 | The store records the purchase on its POS terminal. |
| 2 | The information travels to the acquirer (merchant bank). |
| 3 | The payment network (Visa, Mastercard, etc.) receives the request. |
| 4 | The issuing bank verifies funds, fraud, and limits. |
| 5 | The purchase is approved or rejected. |
| 6 | The business receives authorization almost instantly. |
This entire process usually takes between one and three seconds.
The main participants in a transaction
Many people believe that only the buyer and the seller are involved, but in reality several actors participate.
| Participant | Function |
| Customer | Make the purchase |
| Trade | Sell the product or service |
| Issuing bank | It issues the card |
| Acquiring bank | Processes payments for commerce |
| Card network | Connects both banks |
| Payment processor | Manages the operation technically |
Each person receives different information during the process to maintain safe and efficient operation.
How does the bank make money?
Although many cards offer interest-free periods or rewards, banks generate revenue through various mechanisms.
Interests
If the user does not pay the full balance before the due date, they begin to pay interest on the debt.
Trade commissions
Businesses pay a commission for accepting cards.
This commission typically covers:
- Payment network
- Issuing bank
- Acquiring bank
- Processor
Annual fees
Some cards include memberships or premium benefits.
Why do stores accept cards?
Accepting cards involves paying fees, but it offers numerous advantages.
Benefits
- Higher sales volume
- Customers can buy more easily
- Less cash handling
- Greater security
- Online sales
- International purchases
Several studies show that reducing barriers to card payments encourages adoption by businesses, especially small businesses.
Types of credit cards
Not all of them work the same.
| Type | Features |
| Classical | Basic benefits |
| Gold | Upper limits |
| Platinum | Travel and insurance |
| Signature | Premium benefits |
| Business | Corporate spending |
| Student | Initial credit history |
What is an authorization?
When you buy, the bank doesn’t give you the money immediately.
First, it performs an authorization where it verifies:
- Valid card
- Available limit
- Possible fraud
- Account statement
Only then does he approve the purchase.
Authorization does not mean immediate payment
It is important to understand this difference.
| Authorization | Liquidation |
| Reserve the amount | Actually transfer the money |
| It happens in seconds | It can take hours or days. |
What happens after a purchase is approved?
Once approved:
- The store delivers the product.
- Send all sales for the day.
- The buyer settles the transactions.
- The issuing bank pays.
- The business receives the money minus the commissions.
How do modern cards protect against fraud?
Current cards use multiple layers of security.
Chip EMV
Each transaction generates a unique code.
This makes copying the physical card extremely difficult.
Tokenization
Digital payments replace the actual card number with a device-specific token, reducing the risk of data exposure.
CVV codes
They are mainly used for online shopping.
Anti-fraud systems
Banks automatically analyze:
- Location
- Time
- Record
- Device
- Purchase type
Difference between debit and credit cards
| Feature | Debit | Credit |
| Use your own money | Yeah | No |
| It generates debt. | No | Yeah |
| It can generate interest. | No | Yeah |
| Build a credit history | Bit | Yeah |
| Rewards | Limited | More common |
What happens if a store rejects the card?
The most frequent causes include:
- Insufficient limit
- Expired card
- Communication error
- Suspicious operation
- Offline commerce
- International restriction
In-store shopping vs. online shopping

They typically use:
- Chip
- NFC
- Magnetic strip (increasingly less common)
Online

- Additional verification (such as one-time codes where applicable)
What is contactless payment?
Contactless technology uses NFC.
Benefits:
- Faster
- More comfortable
- Reduces physical wear and tear
- High security through authentication and tokenization in compatible solutions.
What do businesses actually receive?
The business does not receive the full amount.
Example:
| Concept | Value |

The percentage depends on the contract with the acquirer and the type of card.
