With many national governments and businesses such as airports and hotels moving toward e-passports and biometric identification, CIA agents and other country covert ops may have problems moving around the world under assumed identities, reports Gizmodo.

Before 9/11, undercover agents could easily use multiple false passports when moving around a foreign country. Today, with the introduction of biometrics, if an agent has to undergo biometric scans upon entry of a foreign country, he is tied to the the identity on the passport.

Businesses like hotels and car rental agencies request passport information upon check-in and share it with local immigration authorities on a daily basis, meaning that someone who enters the country under one name can’t show up on a registry under a name that doesn’t register as having entered the country.
