Yes, TSA scanners can easily detect large amounts of cash in both carry-on and checked luggage, often appearing as dense, rectangular, or metallic shapes on the X-ray monitor. While the TSA's primary focus is on threats like explosives or weapons, they can identify and inspect large, bundled, or concealed stacks of currency.

Can I fly with 20k cash?

Yes, you can fly with $20,000 cash, but for international travel, you must declare it to U.S. Customs and Border Protection (CBP) by filing a FinCEN Form 105, as any amount over $10,000 needs reporting; for domestic flights, there's no limit, but large sums can trigger extra screening, so keep it in your carry-on and be prepared to explain its legitimate source to avoid seizure, advises USA.gov, DHS.gov, CBP.gov, and Remitly, Alternative Airlines.

Can TSA see my tampon?

No, TSA body scanners generally cannot see inside your body or your tampon/menstrual cup, as the millimeter wave technology doesn't penetrate skin; however, the product itself, especially pads, can create a yellow "alarm" on the scanner's screen, leading to a pat-down for additional screening, so you might get flagged for a closer look but they don't know exactly what it is, just that there's something there.

It's a critical cutoff that ensures enough time for baggage handling, security, and boarding, and missing it can lead to denied boarding, even if you've checked in online.

Is depositing $2000 in cash suspicious?

Depositing $2,000 in cash isn't inherently suspicious and is well below the $10,000 reporting threshold for banks, but it can raise flags if it's part of a pattern (structuring), inconsistent with your normal income, or involves other red flags like frequent large cash deposits from others, leading to a potential Suspicious Activity Report (SAR). To avoid issues, have clear records for the cash's source, like invoices or sales receipts, especially if you deal in cash often.
