Can airport x-ray scanners spot a few cash banknotes such as 3x500 EUR or chip-chipless credit card hidden inside notebook other electronic device?

The ability of airport x-ray scanners to detect cash banknotes or credit cards hidden inside a notebook or other electronic devices depends on several factors:

1. X-ray Scanner Technology:

- Modern airport x-ray scanners use advanced technology that can detect dense materials, including cash and electronic components. However, the effectiveness of the scanner depends on its specific design and capabilities.

2. Amount of Cash and Type of Device:

- The number of banknotes and their denominations can influence detectability. A few banknotes may be harder to spot compared to a larger stack of cash. Additionally, the type of electronic device and its materials can affect how well the scanner can penetrate and reveal hidden objects.

3. Placement of Cash or Card:

- The location of the cash or credit card within the device is crucial. If they are placed in a compartment or area with a lot of other dense materials, it might be more challenging for the scanner to differentiate them.

4. Shielding Materials:

- Some materials can block or absorb x-rays, making it harder to detect hidden objects. If the cash or card is wrapped in metallic foil or placed near other dense materials, it could reduce their visibility on the x-ray image.

5. Operator Experience:

- The skill and experience of the scanner operator play a significant role in detecting hidden items. A trained operator is better equipped to identify suspicious areas and distinguish between different materials on the x-ray screen.

6. Scanner Sensitivity and Calibration:

- The sensitivity and calibration of the x-ray scanner can impact its ability to detect small objects. Regularly maintaining and calibrating the scanner ensures optimal performance.

7. Additional Screening Methods:

- In some cases, if the x-ray scan raises suspicions, additional screening methods may be used, such as pat-downs or hand-held metal detectors, to further examine the item in question.

In general, airport x-ray scanners are designed to detect potential threats and suspicious objects. While they may not be able to identify every single banknote or credit card hidden within a device, they can significantly reduce the risk of smuggling and other illegal activities.
