Can the airport X-ray machine scan money?

Yes, airport X-ray machines can scan money. In fact, X-ray machines are commonly used in airports to scan luggage, including any cash or currency that may be carried by passengers. The X-ray scanner can detect the presence of cash, and airport security personnel may inspect the currency further if they suspect any illegal activity or if the amount exceeds the legal limit set by the country's customs and border control regulations.

It's worth noting that the X-ray machines used in airports are designed to scan for any potential security threats and are not intended to damage or affect the quality of the items being scanned, including cash. However, it's always a good idea to check with your airline or local airport regulations to ensure that you comply with any rules or restrictions related to carrying cash or currency when traveling.
