RFID credit cards: Should you worry about protection?
RFID credit cards are growing in popularity and have already been adopted by major credit card issuers.
These cards use radio frequencies to allow the cardholder to pay at terminals by tapping their card on a card reader as opposed to swiping or inserting their card.
RFID credit cards are considered safe to use, and credit card fraud using RFID readers is rare and difficult to do.
Radio-frequency identification (RFID) credit cards are a type of contactless card technology that allows you to make your payment by simply tapping your card at the payment terminal.
While these types of cards had already begun replacing traditional cards without this technology for many years, the demand for them grew quickly during the COVID-19 pandemic as people were looking for ways to minimize contact with surfaces.
Most major issuers have integrated this technology into all of their new cards, but like any credit card you carry, you should still take precautions to ensure that your card is safe from identity thieves and fraudsters. But if you're wondering how safe RFID credit card technology is in particular, you're in for some good news. Before we get into the safety aspect, however, let's start with understanding how an RFID card actually works.
An RFID credit card is equipped with radio frequency identification technology. This allows your credit card to communicate with a payment terminal using a radio frequency instead of a magnetic strip.
RFID technology allows you to simply tap or wave your credit card near a card reader or ATM. Using this technology to make purchases gives you the ability to complete transactions within seconds. Plus, your card never has to leave your hand, minimizing contact with the card terminal and the likelihood of leaving your card in the reader.
While RFID technology is becoming the norm for new credit cards, not all cards have been updated with the technology. Older cards that might not have hit their expiration date yet, for example, might still be missing this technology. If you're not sure whether your card is RFID-enabled, you can easily check by taking a look at the card.
RFID-enabled cards have a symbol on the front or back of the card that looks like a Wi-Fi icon turned on its side. This symbol is meant to represent the radio frequency used by the card to make it contactless.
If your card has that symbol, you should be able to make purchases with a wave or a tap of your card. To be sure, you can test it the next time you go to a shop, ATM or gas station pump. When you're at the payment terminal, look for the contactless symbol on the card reader, which looks the same as the symbol on your card. Then, simply tap your card on the payment terminal to complete your transaction.
RFID credit cards are considered to be as safe as EMV chip cards, and data theft concerning RFID cards is uncommon. This is because of how these cards transmit information and what information is shared.
Unlike traditional credit cards, RFID cards use one-time codes to complete each transaction. Every time you use your RFID card, a new code is created, thus making it more difficult for your information to be compromised. However, just because theft using this technology is uncommon doesn't mean it's impossible to do.
Because RFID credit cards work via radio frequencies, some thieves have begun targeting these credit cards by using RFID readers. These readers could potentially pick up your card information without your knowledge by getting close enough to your card to pick up on the radio frequency. For this reason, there are quite a few products on the market, such as sleeves and wallets, that claim to have RFID protection.
However, these products are not necessary to keep your RFID credit cards safe. For a person to compromise your card information, they would have to get very close to you — typically a few inches max — with an RFID reader that could pick up the signal. That signal is incredibly weak, so there would have to be practically no barriers between the card and the card reader. This means that if you already have your card in a wallet or bag, it's likely protected enough from the range of an RFID reader.
Plus, even if a reader is able to pick up the signal, it could run into issues with the other contactless cards in your wallet also sending out signals. These readers are typically unable to scan multiple cards at once, so they could have trouble singling out one card to read anyway. On top of that, because of the one-time codes that we mentioned earlier, it's unlikely that a thief could store your card information to use over and over like they could when they have your physical credit card.
Bankrate's take
While it is technically possible for a thief to find a way to skim your RFID card, they would have to work quite hard to do so. If you do find yourself targeted for credit card fraud and identity theft, regardless of how it happens, report the theft immediately. The faster you do so, the more likely that your bank or card issuer will cover the fraudulent charges under their liability policy.
RFID credit cards are some of the most secure credit cards at our disposal, but it's still good to take precautions as with any other credit card. Here are some tips that can help you get started:
Set up mobile alerts for all of your accounts. Mobile alerts will give you a notification any time your card is used, allowing you to immediately identify suspicious charges.
Make sure you have a strong password for your online accounts. If you're worried about losing your password or forgetting it, you can take advantage of a password management app like Dashlane or LastPass. Just avoid saving your password on websites via your browser if possible.
Take the time to review your credit card statements and credit report routinely. These tools document activity in your accounts and give you a clear picture of how your card is being used and what you're being charged for, so it's a good idea to review them each week to catch early signs of fraud. You can get free weekly credit reports by using the government-authorized website AnnualCreditReport.com.
RFID credit cards allow you to pay with a tap, rather than inserting or swiping your card. Special RFID-blocking wallets and sleeves, despite their popularity, generally aren't necessary for security because the technology requires an obstruction-free environment and extreme proximity to the card that's being targeted. In other words, most materials — such as a regular wallet, a purse or a pocket — will prevent the RFID technology from working, making it tough for a scammer to tap your card without your knowledge.
If you don't currently have a card with this technology and want one, consider contacting your card issuer. They could likely send you a replacement card with this feature. Most of today's top credit cards will already have this feature included, but you can always reach out to the issuer to double-check before you apply.

JetBlue is pulling out of the Miami airport, but will remain at FLL. See details
JetBlue Airways will halt service at Miami International Airport, the airline said on Saturday. The Long Island City-based carrier cited poor financial performance. JetBlue has a small footprint at MIA, with one or two daily flights between MIA and Boston. But 'to free aircraft for new routes, we've recently made the decision to end a small number of unprofitable flights including between Boston and Miami,' Derek Dombrowski, director of corporate communications, said in an email statement sent to the Miami Herald. The changes are effective Sept. 3, he said. Travelers booked on cancelled flights 'will have the option to fly via Fort Lauderdale or receive a full refund to their original form of payment,' Dombrowski said. The move was a business decision. 'We continually evaluate how our network is performing and make changes as needed,' Dombrowski said. JetBlue informed MIA of the changes on Friday, Greg Chin, communications director for Miami-Dade Aviation Department, said in a phone call with the Miami Herald on Saturday. He didn't elaborate on other details. JetBlue's Fort Lauderdale presence JetBlue will continue to fly to Boston from nearby Fort Lauderdale-Hollywood International Airport as well as West Palm Beach, Dombrowski said. The airline has a strong presence at FLL. In 2024, JetBlue served about 6.8 million passengers at FLL, down 2.1% from 2023 but still the second largest carrier at that airport, only behind Spirit. It carried 19% of all travelers to and from the Broward County airport. This year, JetBlue remains FLL's second largest carrier. Through April 30, the airline had 2.2 million passengers, even though that's down 6% from the same period in 2024. In 2021, to make a larger bet on South Florida as the COVID-19 pandemic was still in full force, JetBlue expanded at MIA, adding as many as 14 daily flights, including as many as four times a day to Boston. The airline also added direct flights between MIA and New York-JFK, Newark, Los Angeles and Hartford. Since then, JetBlue has scaled back service in Miami due to falling demand. It was also slowed down by the 2024 ruling of a federal judge in Massachusetts that blocked an attempted merger with Broward-based Spirit, citing anti-competitive laws. On Saturday, JetBlue had a total of two arrivals at MIA, each one from Boston, according to the airport's flight tracker. And it had one departure, also to Boston.

Teradyne (NasdaqGS:TER) Revamps By-Laws to Modernize Shareholder Procedures and Director Elections
On June 20, 2025, Teradyne implemented significant amendments to its By-Laws, adjusting nomination and proposal notice windows and clarifying voting standards. Over the past month, Teradyne's stock price moved 9% amid these changes, potentially reflecting investor confidence in enhanced governance practices. Although the broader market has remained flat, the recent gains by the company could suggest that these internal updates resonated positively with market participants, aligning with an overall upward market trend over the past year. This internal shift may have added weight to Teradyne's modest divergence from the market's flat performance. Buy, Hold or Sell Teradyne? View our complete analysis and fair value estimate and you decide. These 17 companies survived and thrived after COVID and have the right ingredients to survive Trump's tariffs. Discover why before your portfolio feels the trade war pinch. The recent amendments to Teradyne's by-laws could potentially reinforce investor confidence, aligning with broader market interests in strong governance. Over a longer five-year span, Teradyne's total shareholder return of 7.61% provides context for its performance, despite the stock's short-term fluctuations. This return contrasts with the company's one-year underperformance, as it lagged behind both the overall US market and the semiconductor industry, indicating room for improvement. The governance changes could influence Teradyne's revenue and earnings positively, particularly in the context of its strategic focus on AI, robotics, and automation. These areas are anticipated to boost revenue, though current geopolitical and tariff concerns could pose risks. Analysts forecast an annual revenue growth of 12.3% and a rise in profit margins to 24.7%, indicating a potential upside, even if challenges persist. The recent share price movement following the changes, while reflective of immediate investor sentiment, shows a notable gap against the consensus price target of US$99.83, which represents a 25.8% potential increase from the current US$74.07. This suggests that investors might be weighing the company's long-term strategic initiatives against current uncertainties.

Fannie Mae chief Pulte sends savage one-word message to Fed's Powell
There's mounting tension in Washington, D.C. over the Federal Reserve's interest rate policy. After cutting interest rates by 1% late last year, Fed Chairman Jerome Powell has taken a decidedly different tack in 2025, holding interest rates steady, and frustrating many, including President Donald Trump, who wants rate cuts now. President Trump has called Powell a "numbskull" for not reducing the Fed Funds Rate, and "Mr. Too-Late" because of the risk that the Fed's hesitancy will put it behind the curve, possibly causing stagflation or worse, a recession. Don't miss the move: Subscribe to TheStreet's free daily newsletter The Fed's dilly-dallying on rate cuts means homebuyers will have to wait for lower mortgage rates, a fact that hasn't been lost on housing market experts, including Fannie Mae Chairman Bill Pulte, who is also director of the Federal Housing Finance Agency (FHFA). Pulte knows a thing or two about the housing market, given he's the grandson of the founder of the mega homebuilder PulteGroup and formerly served on PulteGroup's board of directors. This week, Pulte targeted the Fed's monetary policy, delivering a harsh rebuke and curt message to Chairman Powell that has raised eyebrows. Image source: Bartkowski/Getty Images The Federal Reserve has an important mission to encourage low inflation and unemployment by raising or lowering the Fed Funds Rate. The FFR is the rate that banks charge each other when lending excess reserve balances overnight. Unfortunately, its dual mandate is easier said than done. Often, low inflation and unemployment are contrary goals. Higher rates lower inflation but increase job losses, while lower rates decrease unemployment but increase inflation. Related: Fed interest rate cut decision resets forecasts for the rest of this year We've witnessed that dynamic in real time over the past five years. At risk of surging unemployment due to the Covid pandemic, the Fed doubled down on its zero-interest rate policy of low rates. The move worked, helping the U.S. avoid a recession or worse. However, low rates (and stimulus payments) caused inflation to spike in 2021. At the time, Fed Chair Powell initially and infamously referred to inflation as 'transitory;' however, he was forced to switch gears and embark on the most aggressive rate hikes since the 1980s after inflation skyrocketed to 8% in June 2022. The higher rates have sent inflation below 3%; however, they've done so at a cost, given emerging cracks in the jobs market. The U.S. unemployment rate has moved up to 4.2% from 3.4% in 2023, and over 696,000 layoffs have been announced this year through May, up 80% year over year, according to Challenger, Gray, & Christmas. There's also increased evidence that the economy is weakening. ISM's latest manufacturing and services PMIs, which measure economic activity, were below 50, suggesting contraction in May. A concerning job market and potential economic slowing aren't great recipes for consumer and business spending, yet the Fed has kept its finger off the rate cut trigger, citing inflation uncertainty amid recently enacted tariffs. Related: Major housing expert predicts huge change to mortgage rates in 2026 Since February, President Trump has placed 25% tariffs on Canada, Mexico, and autos, a 10% baseline tariff on all imports, and stiff tariffs on China, a significant trade partner that supplies just about everything from clothing to car parts. While China's tariffs have retreated from a sky-high 145% in April that effectively shut down trade, they remain at 30%. Worries that tariffs may cause inflation to reassert itself in the coming months have Fed Chair Powell a bit boxed in, given that rate cuts to shore up the economy may add to possible inflationary fires this year. Fed Chair Powell argues that a wait-and-see approach makes sense, given that unemployment is historically low and the economy, while showing some worrisome signs, is still expected to grow by 3% this quarter. Related: Forget tariffs, Fed interest rate cuts may hinge on another problem "The effects on inflation could be short-lived - reflecting a one-time shift in the price level. It is also possible that the inflationary effects could instead be more persistent," said Powell after holding rates steady on June 18. "Avoiding that outcome will depend on the size of the tariff effects, on how long it takes for them to pass through fully into prices, and, ultimately, on keeping longer-term inflation expectations well anchored." The worry over tariffs isn't shared by Fannie Mae Chairman Pulte. After Powell held interest rates at their current 4.25% to 4.50% range, he blasted Powell, calling for immediate interest rate cuts to lower mortgage rates and support the housing market. "Jerome Powell is a main reason for the Housing Supply Crisis in this Country," wrote Pulte on X. "By improperly keeping interest rates high, Jerome Powell is trapping homeowners in low-rate mortgages and choking off existing home sales - directly fueling the housing supply crisis. He must lower rates." Pulte is, at a minimum, correct anecdotally that the housing market is in a crisis, especially with first-time homebuyers who struggle to come up with enough money for a down payment, given supply shortages have propped up home prices, and can't afford monthly mortgage payments. More Economic Analysis: Federal Reserve prepares strong message on long-term interest ratesMassive city workers union approves strikeAnalyst makes bold call on stocks, bonds, and gold Mortgage rates typically run 2% to 3% higher than the 10-year Treasury note yield, and the Fed Funds Rate highly influences the 10-year yield. As a result, 30-year mortgage rates have risen to roughly 6.8% from 2.7% in early 2021 before Powell raised rates to fight inflation. In April, the median price for a new home exceeded $407,000, up from $310,000 five years ago. Meanwhile, according to Bankrate, the average mortgage payment doubled to $2,207 in 2024. With housing affordability so challenging and the Fed firmly in the "no cut" camp, Pulte sent a powerful message to Powell. "Americans are sick and tired of Jerome Powell. Let's move on!" wrote Pulte. "Funny thing is Jay Powell is talking right now about the housing market - he has no clue what he can do for the housing market. And he's not listening to the people who help lead the housing market." His blunt advice to Powell? "RESIGN," said Pulte.
