Many travellers worry about the potential effects of airport X-ray machines on their electronic devices and personal items. One common item that people often question the safety of is the EZPass, a toll road transponder. The EZPass is a device that sends and receives signals to communicate with toll booths. Despite concerns, the EZPass is an RFID chip, similar to those found in credit cards and security badges, and does not have its own power source. Therefore, it is highly unlikely that an airport X-ray machine will damage an EZPass.

What You'll Learn
X-ray machines cannot damage EZPasses
X-ray machines are commonly used in airports to screen luggage and ensure the safety of passengers. While X-ray machines emit a small amount of radiation, they are generally considered safe for most items.
In the context of EZPasses, there is no need to worry about potential damage from airport X-ray machines. EZPasses are transponder devices that send and receive signals to toll booths, allowing for convenient toll road payments. These transponders are designed to be durable and are not sensitive to X-ray exposure.
The concern about X-ray damage primarily arises with electronic devices and items such as film photography. High-speed film (ISO 800 and above) is particularly sensitive to X-ray radiation, which can cause fogging and damage to undeveloped film. However, EZPasses do not contain any components that are susceptible to radiation damage.
Additionally, EZPasses are RFID-enabled, which means they remain inactive until they are activated by an RFID reader. This further reduces the likelihood of any potential interference or damage from X-ray machines.
While some travelers choose to wrap their EZPasses in foil as a precautionary measure, it is not necessary for the protection of the device. X-ray machines in airports are routinely used to scan various electronic items, and EZPasses are not known to be affected by this process. Therefore, travelers can rest assured that their EZPasses will not be damaged by airport X-ray machines.

EZPasses are RFID chips, similar to credit cards
EZPasses are RFID (Radio Frequency IDentification) chips, similar to the technology used in credit cards, security badges, and new US passports. They are powered by the signal they receive from the antenna at the toll booth, and do not have any power of their own. This means that they cannot transmit on a plane as there is no signal to power them.
RFID technology can be either active or passive. Active RFID tags have batteries and emit their own identification signal over a longer distance, while passive tags have no battery and a shorter range. EZPasses are active RFID tags, as they contain a microchip, a battery, an antenna, and the ability to transmit and receive signals. This allows them to work seamlessly with the automatic tolling system.
The X-ray machines used to check carry-on items at airports will not damage electronic media. These modern carry-on X-ray systems are considered film-safe, meaning the amount of X-ray radiation is not high enough to damage film or electronic devices. Since EZPasses are RFID chips, they should not be damaged by the X-ray machines at airport security.
However, it is important to note that EZPasses may attract extra attention from TSA agents, as they could be considered a transponder, or a device that sends and receives signals. To avoid any issues, it is recommended to take the EZPass out of your bag before going through security, and to keep it separate from other electronics or wires.

TSA agents may recognise EZPasses
X-ray machines at the airport will not damage your EZPass. However, TSA agents may recognise EZPasses as they are commonly used tollway transponders. If you are concerned about your EZPass being recognised, you could put it in a foil bag to prevent it from communicating while you are in the air.
TSA agents use unpredictable security measures, and all travellers will be screened. You may be asked to open up your packaging for inspection, but this is at the discretion of the TSA agent. If you are nervous about your EZPass being damaged, you could consider carrying it in your hand luggage.
If you have questions concerning your TSA PreCheck status, you can reach out to the TSA Contact Center at (866) 289-9673, or via Twitter, Facebook Messenger, Apple Business Chat, or by texting "Travel" to 275-872.
It is recommended that you remove electronic equipment from your bag and put it separately in a tray for screening.

EZPasses cannot transmit on planes
EZPasses are transponders, which are devices that send and receive signals. Some people are concerned that EZPasses may transmit signals on planes, causing problems with the aircraft's electronics. However, this is not the case. EZPasses are RFID devices, which means they only transmit signals when activated by an RFID reader. Therefore, EZPasses cannot transmit on planes because there are no RFID readers present to activate them.
The EZPass transponder simply listens for a signal from a toll booth and then sends its ID. This means that even if an EZPass is not wrapped in a shielding bag, it will not cause any issues on a plane. The likelihood of a plane getting close enough to a toll booth for an EZPass to be charged is extremely low. Even if an EZPass is activated, it is no more dangerous than a credit card with an RFID chip or an employee ID badge.
Some people choose to wrap their EZPasses in tin foil to prevent them from communicating while in the air. However, this is not necessary, as EZPasses cannot transmit without a signal from a toll booth antenna. Wrapping an EZPass in foil may actually cause more issues, as it can make the item appear opaque on an X-ray scan, leading to a bag check.
While EZPasses are allowed on planes, it is important to note that the final decision on whether an item is permitted through a checkpoint rests with the TSA officer. In general, TSA officers tend to view unfamiliar items as potentially dangerous, especially if they have wires. Therefore, it is recommended to take proactive measures, such as removing the EZPass from your bag, to avoid additional bag checks.

X-ray machines cannot damage film or electronic media
X-ray machines emit a small amount of radiation, which has been known to fog and damage undeveloped film. However, the risk of damage is higher with higher-speed films (ISO 800 and above), and even lower-speed films can be affected by multiple exposures to X-rays. That said, some photographers have reported that their film has passed through multiple X-ray machines with no noticeable difference in their developed shots.
Similarly, X-ray machines are not known to damage electronic devices. The FDA has received some reports of electronic medical devices being damaged during CT scans, but this is due to interference from radiation, not the X-ray machine itself. The probability of any issues is extremely low, and doctors recommend X-ray procedures, including CT scans, for people with electronic medical devices for medical reasons.
When it comes to airport security, X-ray machines are commonly used to scan luggage and electronic devices. While it is possible for an X-ray machine to damage a GPU or other electronic devices, it is unlikely. Some people choose to hand-carry their valuable electronic devices to avoid any potential damage during transit. However, most airports require passengers to remove electronic equipment from their bags and place them in separate trays for scanning.
Overall, while X-ray machines emit radiation that could potentially damage film or electronic media, the risk of damage is low. In the case of electronic devices, any damage is typically due to interference from radiation during CT scans rather than standard X-ray procedures.

Frequently asked questions
No, EZPasses use RFID chips, just like credit cards, security badges, and US passports. These chips are powered by external signals, and since there are no signals present on a plane, the EZPass cannot transmit. Therefore, it will not be damaged by airport X-ray machines.
Putting your EZPass in a foil bag might make it appear opaque on the X-ray, which could lead to additional bag checks. It is best to leave it accessible and away from other electronics to make it easier to identify on the X-ray.
No, your EZPass will not be activated by the RFID reader at the airport. It is no more dangerous than carrying a credit card or an employee ID with an RFID chip.
No, all modern carry-on X-ray systems are considered film-safe. This means that the amount of X-ray radiation is not high enough to damage electronic devices.
