chips readable by long range rfid skimmer

 

Key takeaways

  • A long-range RFID skimmer is a device that a fraudster uses to intercept a connection between an RFID chip and a reader.
  • Devices like keys, fobs, credit cards, and even passports use RFID technology.
  • To protect yourself against RFID skimming, you can line your RFID devices with foil or invest in an RFID-blocking jacket or wallet.
  • If you’re interested in providing your residents with an alternative to RFID credentials, you can invest in other methods of access control, like smartphone-based access.

 

Wireless technology has helped simplify tasks and make the world a more convenient place. Whether we’re talking about wireless headphones, contactless payments, or fobs and readers, wireless devices are becoming more prominent.

But is wireless technology like RFID safe? Turns out, you might have to watch out for intercepting tools, like RFID skimmers, that put your information at risk.

In this post, we explain what a long-range RFID skimmer is and how it works. Then, we help you protect yourself from RFID skimming by picking out alternative credential types.

What is a long-range RFID skimmer?

A long-range RFID skimmer is a device that allows somebody to intercept a transmission between an RFID chip and its reader.

Across fields and industries, wireless technology is becoming more popular — and specific methods of wireless transmission come with benefits and drawbacks. You might have used Bluetooth, WiFi, or NFC (near-field communication) technology in your daily life. In fact, RFID, or Radio Frequency IDentification, is just another way to transmit information wirelessly.

Devices that use RFID chips include:

  • Credit cards
  • Key cards
  • Fobs
  • Passports

Unfortunately, RFID manufacturers are up against scammers and fraudsters who want unsecured access to people’s transmissions.

In terms of RFID devices, criminals most often try to intercept credit card payment information or credential data that allows them access into a building.

How do RFID skimmers work?

RFID skimmers work by triggering an RFID chip and recording the information stored on it.

There are two main types of RFID chips: active and passive. Active chips are connected to their own batteries, but passive chips need to be triggered by electromagnetic waves. As a result, a long-range passive RFID reader needs to be powerful enough to trigger a chip.

A fraudster might deploy a skimming device in a variety of ways. For example, a common method of RFID skimming is placing a reader close to where a lot of cards are frequently used, like near a commercial or residential property entrance. Then, as people present their cards, the skimmer records their card data.

 

What is the longest range for an RFID reader?

Active RFID readers don’t rely on proximity. As a result, they can read from up to 300 feet away. However, if a signal repeater is employed, RFID readers can read up to 1,500 feet away.

 

What is the range of RFID skimmer?

Unfortunately, long-range RFID skimmers don’t need to be directly next to an RFID credential to read its information. Instead, most skimmers can read from a distance of up to 19 inches, or 50 centimeters. However, users can boost the power of an RFID skimmer with antennas or other long-range transmission technologies to try to collect data from further away.

How can you protect yourself against RFID skimming?

You can protect yourself against RFID skimming by covering your credential in foil or investing in RFID-blocking materials — such as carbon fiber.

However, while the technology to skim an RFID device certainly exists, the threat of a long-range RFID credit card skimmer is vastly overstated.

Even the best RFID long-range readers would struggle to successfully copy data illegitimately. Real-world conditions like distance, weather, and the presence of hundreds of other radio signals in an area make capturing somebody’s RFID data from afar much harder than it sounds.

While the technology to capture RFID data exists, criminals are more likely to use tactics like social engineering and phishing attempts to illegally obtain information.

With that being said, let’s further explore the best methods to protect yourself from a long-range RFID scanner:

 

Covering credentials in foil

While foil does succeed in blocking all RFID frequency ranges, this method comes with a few downsides. For instance, residents who want to use their credential would have to spend time uncovering their credential and covering it back up again.

Moreover, because one of the benefits of RFID access is the convenience of a single tap or touch, some residents may find that the security benefits of foil are too much of an inconvenience.

 

RFID-blocking materials

Manufacturers of RFID-resistant materials are producing a variety of products to meet consumer demands for safety and security. Security-conscious tenants can choose between RFID-blocking wallets, fanny packs, and even jeans.

 

Alternatives to RFID credentials

While the risk of RFID skimming is low, tenants might be preoccupied with the threat of skimming if your property uses RFID credentials. As an alternative, you might enable additional ways to open the door, like smartphone-based access.

A resident’s primary concern with an RFID credential might be the threat of a long-range EM RFID skimmer. However, as a property manager, RFID credentials like fobs or cards present a different set of problems.

An RFID fob might enable features like wireless or contactless entry with and higher levels of security. But there’s one way an RFID fob and an old-school brass key are the same: residents might still lose them!

So, to cut down on time spent on key management, the best way to use RFID access on your property is in tandem with other methods of access. You might consider a cloud-based access control system with a smartphone app. Moreover, a smartphone-based system enables residents to enter their building even if they’ve lost one physical credential — such as an RFID card or fob.

Further, by cutting down on the number of RFID devices used on your property, you can spend less time on programming and issuing new RFID fobs to tenants and more time focused on tenant satisfaction.
