How do I scan cards and know when it have been successfully evaluated, without making an API call?
There are a few different ways to scan cards and determine whether they have been successfully evaluated without making an API call. Here are a few options:
Use an SDK: Many card scanning SDKs offer callbacks or events that are triggered when a successful scan has been completed. For example, the card.io SDK provides a “didScanCard” callback that can be used to notify your app when a card has been successfully scanned. This allows you to handle the success case without making an API call.
Validate the card number: Another approach is to use the Luhn algorithm to validate the scanned card number. The Luhn algorithm is a simple checksum formula that is used to validate credit card numbers. By checking whether the scanned number passes the Luhn algorithm, you can be reasonably certain that the card number is valid. This approach does not guarantee that the card is actually valid or has sufficient funds, but it can be a quick way to determine whether the card number was scanned correctly.
Use a local database: If you have access to a database of valid card numbers (such as a list of test credit card numbers), you can compare the scanned number to the database to determine whether it is valid. This approach is similar to the Luhn algorithm, but provides more accurate results since it checks against known valid numbers.
Implement visual feedback: Another way to indicate a successful scan without making an API call is to provide visual feedback to the user. For example, you could display a green checkmark or a message indicating that the scan was successful. This approach does not provide any guarantees that the card is valid or has sufficient funds, but it can help the user feel more confident that the scan was successful.

How does scanning a card work?
Scanning a card typically involves using a device to read the information stored on the card’s magnetic stripe or chip, which is then processed by a computer system to determine the card’s validity and complete a transaction or provide access to a secure area.
The process may vary slightly depending on the type of card and the specific device being used, but generally, it involves the following steps:
The card is inserted or swiped through a card reader or scanner, which can be a physical device or an app on a mobile device.
The reader or scanner detects the magnetic stripe or chip on the card and reads the encoded information, such as the cardholder’s name, account number, expiration date, and security code.
The information is transmitted to a computer system or payment gateway, which verifies the card’s validity and checks whether there are sufficient funds or credit available for the transaction.
If the card is valid and the transaction is approved, the computer system or payment gateway sends a confirmation message back to the reader or scanner, which displays the result and completes the transaction.
Overall, scanning a card is a quick and convenient way to process payments or access secure areas, and it relies on sophisticated technology to ensure the security and accuracy of the transaction.
What device is used to scan credit cards?
A device commonly used to scan credit cards is called a card reader or credit card scanner. There are several types of card readers, but most commonly used are magnetic stripe readers and EMV chip card readers.
Magnetic stripe readers are used to read the information stored on the magnetic stripe located on the back of the credit card. The information is then transmitted to a payment processing system for verification.
EMV chip card readers are used to read the information stored on the embedded microchip on the front of the credit card. This type of card reader provides greater security than magnetic stripe readers, as it generates a unique code for each transaction to prevent fraud.
How can I protect my card from being scanned?
To protect your card from being scanned, you can take the following measures:
Use RFID-blocking wallets or sleeves: RFID (Radio Frequency Identification) technology is used in contactless cards to allow them to be scanned wirelessly. RFID-blocking wallets and sleeves are designed to block the signals emitted by your card, making it more difficult for thieves to steal your information.
Keep your card in a protective case: You can also use a protective case to shield your card from being scanned. This can be as simple as placing your card in a small metal case, which will block RFID signals.
Use a card with EMV chip: EMV (Europay, Mastercard, and Visa) chips offer stronger security than traditional magnetic stripe cards. They encrypt your payment data so that it’s more difficult for thieves to steal your information.
Be mindful of where you use your card: Avoid using your card in areas that seem unsafe or unsecured. For example, if you’re at an ATM, make sure there’s no one standing too close to you, and always cover the keypad when entering your PIN.
Check your statements regularly: One of the best ways to protect yourself against card fraud is to check your statements regularly for any unauthorized charges. If you notice anything suspicious, report it to your bank immediately.
