Today a visa and passport are almost always both essential when traveling internationally. In order to prevent criminals from moving openly, these travel documents have been required for many years. Although new methods will likely not completely replace the passport system that we have been accustomed to today, they will add more security measures that need to be passed.The move from physical passports to digital ones is via the use of biometric devices. The biometric technique measures a person’s face in order to find a match and pull their profile, and this approach prevents passport fraud. Recent breakthroughs have allowed this to happen accurately in only a few seconds from the first read. In order to keep analyzing a person’s face until a precise match is found, a high resolution video camera can be used to keep reading and finally make an exact match. Faking the system with these devices becomes near impossible, and merging this method with the traditional passport will deter most criminals.One of the technologies that is being considered with biometrics is utilizing an RFID chip in a physical passport. This chip is similar to other near field technologies that transfer personal information when asked wirelessly. Though these chips do not do anything cutting edge, they offer a great double check of US passports and biometric information that is presented when traveling.Although there are always new technologies being developed, the biggest challenge with any of them is creating something that is as difficult as possible to replicate. Innovative technologies always associate with advanced methods of piracy and programming, so officials have a difficult time determining how to lock down digital technology. These systems could be put at risk, so they must implement methods for expanding in the future that will be like the markings that make physical passports difficult to forge.Visiting other countries is also becoming more secure by means of what they call e-visas. These go right alongside of the passports, but are tricky to implement since a standard needs to be adapted. For example, traditional China visas are not near as secure as an e-visa, and it would also make traveling simpler as well. It could take many years before they replace traditional paper visas, but the day is on its way when cheap technology can be extremely accurate and reliable as well. Luckily the amazingly fast advances in small computer chips these days have made everything technology related speedier and cheaper. In spite of these advancements, other countries without any sort of technology backbone would be left out, instead making the countries that implement them more secure than the rest.
