"A number of countries around the world are introducing technology-enhanced passports designed to prevent or greatly inhibit forgery and counterfeiting. One of the key components is the Radio Frequency Identification (RFID) memory chip. Residence visas and national identity cards are also beginning to include the chips. The reason is that the chips are supposed to be nearly impossible to forge or tamper with. They are intended to store coded data, including biometric data such as fingerprints, face and iris scans, as well as all other necessary details to prove who the holder of the document is."
