How to self-test passport electronic chip

If your passport is damaged by the external environment (such as water, stains, breakage, etc.). ), it is recommended to replace it in time.

Electronic passports use near field communication (NFC) chips to carry biological information.

Many modern smartphones include NFC readers, which enable them to read data from their e-passports-if you can read data, your e-passports are running. If not, it may be damaged.

There are many applications that can use NFC to read data in passports, such as NFC TagInfo of Android. The information on the NFC chip is protected by a password, which consists of your passport number, birth data and passport validity period, so you need to manually input these contents to display NFC data.

At present, no country has forced the use of e-passports to enter the country.

In some countries/regions, such as SmartGate and global entry, e-passports need to use automatic fast track. If you don't have a valid e-passport, you won't be able to use these channels, but at least in Australia, if/when you can't use SmartGate, you will enter the country through normal ordinary channels.

Electronic chips can be read, and there is no problem in entry and exit, and domestic border inspection will not be blocked by vague entry and exit stamps of other countries.

As for foreign immigration law enforcement agencies, they also know that passports will be damaged to varying degrees during travel, and they are usually not embarrassed by vague entry and exit seals in a small area. If you ask a question, answer it truthfully and pass it with a high probability.

Experts pointed out that e-passport is a kind of electronic certificate with biometric technology as its core. A special electronic chip is built into the existing paper passport, which can not only store basic information such as name and birthday, but also store personal biometric data such as fingerprints, irises and facial images. It can identify passport holders quickly and accurately with special equipment. E-passport can not only minimize the possibility of forging passports, prevent terrorists from getting away with it, but also speed up customs clearance.
