Do RFID-blocking travel wallets actually protect my passport?

Most modern passports already contain a metallic shield in the cover, and documented real-world skimming of e-passports is rare. RFID-blocking layers in these wallets mainly add peace of mind and protect contactless credit cards stored alongside your documents. The candidate pool here advertises RFID blocking widely, but none of the supplied signals include independent lab verification of blocking effectiveness, so treat the claim as a feature, not a guarantee.
