Credit card readers extract information from a customer’s credit or debit card, transmit it to the payment processor, and collect information from the customer’s bank in return. The information from the card reader is sent to the bank account to be used to make a payment. In the case of credit cards, there are two types of readers: magnetic stripe readers and touch-screen readers.
A magnetic strip reader is a device that uses a magnetic field to read a card‘s magnetic stripes. Touch-screens are a type of reader that allows a user to interact with the reader using a stylus or a finger. The reader can also be used in conjunction with a mobile phone or tablet to scan a barcode on a credit card.

What is a card reader and how does it work?
Credit card readers extract information from a customer’s credit or debit card, transmit it to the payment processor, and collect information from the customer’s bank in return. The funds are sent to a bank account if the card reader is able to detect them. In the case of credit cards, the credit card issuer is the company that issues the cards.
The card processor is a third-party service provider, such as Visa, MasterCard, American Express, Discover, or JCB, that processes the transaction and stores the information in a database for later use by the issuer and the merchant. In some cases, a merchant may be able to use the database to verify the identity of a cardholder, but this is not always possible.
For example, some merchants may not have the ability to authenticate cardholders‘ identities, so they may rely on the data stored in the databases to determine whether or not a transaction has been made. This is known as “card-not-present” (CNP) fraud and is one of the most common types of fraud. CNP fraud occurs when a fraudster uses a stolen card to purchase goods or services that are not available at the time the fraud is committed.
How does a card reader know my PIN?

Do you need WiFi for a card reader?
The short answer is that your card reader doesn’t need the internet. All your card readers do is capture a customer’s credit card or debit card details and send them to the card issuer. The long answer to this question is that it depends on the type of card you’re using.
If you use a magnetic stripe card, then yes, you will need a WiFi connection. However, if you are using an EMV (Europay, MasterCard, Visa, American Express, Discover) card then you don’t really need to worry about it. You can just use your phone to scan the barcode and you’ll be good to go.
Does a card reader work with any card?
You can only use your own bank card and PIN when using someone else’s card reader, even if it’s from another bank. If you want your own security, you should only use a card reader from a trusted source.
If you are using a debit card, it is important that you do not use the same PIN number for both your debit and credit cards. If you have multiple cards, use different PIN numbers for each card.
You should also be careful not to share your PIN with anyone else, as this could be used to access your bank account.
