Prevent contactless card theft by using RFID-blocking wallets or sleeves to disrupt radio signals, enabling instant bank transaction alerts, and monitoring statements regularly. For higher security, use mobile payments (Apple Pay/Google Pay) which require biometric authentication and, if possible, keep cards in front pockets or bags to prevent unauthorized scanning in crowded areas.

How to stop contactless card theft?

Line your wallet or cardholder with tin foil to block scamming devices from reading your card.

Don't let anyone take your card out of sight while taking a payment – even for just a few seconds.

What is the 15 3 credit card trick?

The 15/3 credit card payment method is a strategy to potentially boost your credit score by making two payments per billing cycle: one about 15 days before your statement closes (to lower reported utilization) and another around 3 days before the payment due date (to cover the rest and avoid late fees), though its actual impact on credit scoring is debated. It works by keeping your reported balance lower when the card issuer reports to bureaus, but experts note the specific timing isn't magical, and focusing on the reporting date is key. 

Is tapping your card safer than inserting?

Yes, tapping your card is generally considered safer than inserting it because it uses tokenization and encrypted one-time codes, preventing your actual card details from being exposed to the terminal and reducing the risk of skimming, keeping your card in your possession at all times, and often requiring biometric authentication with mobile wallets, though both methods are secure due to EMV technology. While both tap and insert (chip) use strong EMV security, tapping avoids physical contact with potentially compromised readers and keeps your data encrypted for each transaction, making it a superior choice for security and hygiene. 

What is the 2/3/4 rule for credit cards?

The 2/3/4 rule is a guideline, primarily used by Bank of America, that limits how many new credit cards you can get: no more than 2 in 30 days, 3 in 12 months, and 4 in 24 months, helping to prevent over-application and manage hard inquiries on your credit report. While not universal, it's a useful benchmark for responsible card application, though other banks have different rules (like Chase's 5/24 rule).
