How biometrics works to help you get through airport security in a hurry

Question: I recently had surgery on my hand and am quite certain that the handprint will no longer match that on the Global Entry database. I have two international trips coming up and I'd really like my Global Entry to be up to date. Answer: Brown doesn't have to do anything to use his Global Entry privileges, which include expedited re-entry into the United States and screening at domestic airport security, all for 100 for five years. Customs and Border Protection, which administers Global Entry, said it is fingerprints, not handprints, that are used for identification. The re-entry kiosks at immigration, a spokesman said, use four fingerprints from one hand to validate who you are.
