Over 100 countries in the world use e-passports. The US has for a number of years. Canada is just coming on board as one of the last G8 nations to do so.
ePassports contain embedded computer chips. More specifically an RFID chip (Radio Frequency Identification). These chips can contain information such as name, date of birth, gender, and digital photograph. They can also contain biometric information such as iris scans and fingerprints.
Simply opening up your passport and being in the vicinity of an RFID reader opens you up to the possibility of having your information scanned.
Unfortunately passports need to be frequently taken out and opened when traveling for customs, hotels, car rentals, etc.
It is recommended that you store these new passports in a special sleeve to block RFID signals.
Many other cards now being issued contain RFID chips, example Nexus.
Do you agree with storing personal information in RFID chips?
