What You'll Learn
X-ray scanners can detect cash in large amounts
While airport scanners are not designed to explicitly detect cash, X-ray scanners can identify large amounts of currency notes. When luggage passes through an X-ray scanner, the contents are displayed on a screen based on their density and material composition. Currency notes, especially in large quantities, stand out on the X-ray image due to their uniform rectangular shape. This distinct appearance can prompt security personnel to conduct further inspections.
It is important to note that the primary goal of airport security is to ensure the safety of passengers and not to invade their privacy. However, when large amounts of cash are detected, security officers must balance privacy concerns with legal obligations, particularly in the context of anti-money laundering (AML) measures. Airports are considered high-risk areas for the movement of illicit funds, and the detection of large sums of cash can play a crucial role in preventing financial crimes.
Additionally, advanced imaging technology (AIT) scanners used in airport security are designed to create detailed images of a passenger's body to identify concealed items. While these scanners are not specifically intended for detecting cash, they can reveal unusual bulges or shapes if a passenger is carrying a substantial amount of money. This may also prompt further inspection by security personnel.
To avoid any potential issues, it is recommended to declare any large sums of money and comply with the regulations of the country or region you are travelling to. It is also advisable to distribute cash across different luggage items to reduce the risk of theft or loss. By following these guidelines, travellers can ensure a smoother journey through airport security while adhering to legal requirements.

Advanced Imaging Technology (AIT) scanners can detect unusual bulges
Advanced Imaging Technology (AIT) scanners are an integral part of airport security, helping to ensure travel safety and security by staying ahead of evolving threats. They are designed to detect a wide range of threats to transportation security in a matter of seconds, protecting passengers and crew.
AIT scanners use millimeter-wave technology to detect metallic and non-metallic objects concealed under clothing. They create detailed images of a passenger's body to detect concealed items. While not specifically designed to detect cash, if a passenger is carrying a large sum of money on their person, the scanners may reveal unusual bulges or shapes that could prompt further inspection.
AIT scanners are particularly useful for passengers with joint replacements or other medical devices that would regularly set off a walk-through metal detector, as these will not alarm the AIT. The scanners have also improved the passenger experience, with a more comfortable and dignified scan procedure that does not require passengers to raise their hands in the air.
The high-resolution imaging capabilities of AIT scanners mean they can detect opaque objects that may be transparent to X-ray technology, including potential contraband or threat materials. This technology does not expose people to ionizing radiation and emits far less electromagnetic energy than a modern mobile phone or Wi-Fi router.

Metal detectors can detect metal items accompanying cash
Although cash is not metallic, metal detectors at airports can detect metal items accompanying cash, such as money clips or the metal lining of a wallet. Currency notes, especially in large amounts, have a distinctive appearance on X-ray images, appearing as stacks of uniform rectangular shapes. Advanced Imaging Technology (AIT) scanners, on the other hand, create detailed images of a passenger's body to detect concealed items. While not designed to detect cash, these scanners may reveal unusual bulges or shapes that prompt further inspection.
Metal detectors can detect the presence of cash through the magnetic inks used in banknotes. These inks are typically used by vending machines to verify the authenticity of a note. However, large bundles of notes can contain enough magnetic material to be detected by metal detectors, allowing authorities to catch individuals attempting to smuggle cash.
The detection of cash through metal detectors has been a long-standing urban legend, with conspiracy theories suggesting that the security strips in US banknotes allow government agencies to track currency. Although these strips are made of plastic, physicists at the University of Washington in Seattle found that ordinary handheld metal detectors could detect dollar bills from a distance of 3 centimetres.
It is important to note that airport scanners are not specifically designed to detect cash but rather to identify items that pose a threat to aviation security, such as weapons or explosives. However, the detection of large sums of cash can be crucial in preventing money laundering and other financial crimes. Security personnel are trained to observe passenger behaviour and may conduct additional scrutiny and baggage checks if suspicious behaviour is detected.

Behavioural indicators can prompt additional checks
While airport scanners are not designed to detect cash, large amounts of money can be seen on X-ray images as stacks of uniform rectangular shapes. Advanced Imaging Technology (AIT) scanners can also reveal unusual bulges or shapes on a passenger's body that could indicate they are carrying large sums of money.
Behavioural indicators are a crucial component of security screening processes and can prompt additional checks. Security personnel are trained to identify a range of behavioural indicators that may be associated with stress, deception, or hostile intent. For example, someone who is dressed in disguise or gives nervous or conflicting responses to routine questioning may be selected for additional screening. The way a flight is booked can also be a factor—using cash for last-minute international flights might be seen as an attempt to remain anonymous.
Random security checks are also used as a deterrent against potential threats. These checks are not based on specific risk indicators but rather on the unpredictability of being selected for additional screening. This helps to distribute security measures more evenly across all passengers and can catch dangerous individuals who might otherwise slip through.
In addition to behavioural indicators, security personnel may also consider a passenger's method of payment and how their flights were booked. For example, using cash for last-minute international flights might be flagged as suspicious.
Overall, the combination of random selection and specific criteria, including behavioural indicators, is used to identify passengers for additional checks and maximize safety while minimizing risk.

Manual inspections can uncover cash hidden in luggage
While airport scanners are not designed specifically to detect cash, large amounts of currency notes can be easily identified on X-ray images due to their distinctive appearance. Cash appears as stacks of uniform rectangular shapes, which can prompt further investigation by security personnel.
If an X-ray image raises suspicions, security officers may conduct a manual inspection of the luggage, which can uncover cash hidden within. During a manual inspection, a Transportation Security Officer (TSO) physically opens the bag and performs a thorough search. This may be accompanied by a pat-down inspection of the passenger's body, which can include sensitive areas such as the breasts, groin, and buttocks.
The primary goal of airport security is to ensure the safety of passengers and staff, and this sometimes requires balancing privacy concerns with legal obligations. Airports are high-risk points for the movement of illicit funds, and security personnel are trained to observe passenger behaviour for signs of nervousness or deception, which may lead to additional scrutiny and baggage checks.
To facilitate the inspection process, passengers are advised to use TSA-approved locks, which can be opened without damage during a manual inspection. Additionally, passengers should refrain from using decorative items on their luggage, as these can interfere with scanning machines. By following these guidelines and cooperating with security measures, travellers can help ensure a smooth and efficient inspection process at the airport.
