Microchips in payment cards improve security by generating unique transaction codes

Magnetic strips store unchanging data that is easily cloned, but microchips act as miniature computers that encrypt sensitive data. They also resist fraud by creating data unique to each transaction, preventing duplication.

Chip technology replaced magstripes to stop easy card cloning and fraud

The magstripe on bank cards always gives the same data, making it simple to copy using a device called a grabber. In contrast, embedded chips create a unique code with every transaction, making it much harder to clone or steal card information.

China is making a deliberate push towards becoming a cashless society, making digital payment services like Tencent's WeBank even more valuable.

Visualize how passkeys, which rely on asymmetric cryptography to authenticate users, work

After using biometrics or a PIN to access the private key stored on a device, it is combined with a random number generated by the site to produce a cryptographic signature. This signature is verified using the site's public key, allowing a user to log in without entering a password. This reduces the risk of fraudulent messages—phishing attacks—and data breaches.

Worldcoin: the cryptocurrency collecting biometric data

An ambitious project launched by OpenAI's founder Sam Altman, Worldcoin aims to provide a global financial and identity network based on proof of personhood through biometric scanning of individuals' irises.

Why there are microchips in credit cards

Credit cards have evolved significantly since their invention in 1950, but security lagged in the US for years. Despite handling only a quarter of global transactions, the US once accounted for half of all credit card fraud.

CT scanners at airports take images across energy bands to identify baggage contents

Old X-ray scanners' inability to distinguish between water and explosives has driven strict liquid bans and longer wait times through airport security. New scanners combine multi-angle images across the energy spectrum to determine an object's density and atomic composition for improved threat detection.

Gas stations top the list of riskiest places to use a debit card

Unlike credit cards, debit cards withdraw funds directly from your checking account, and federal laws provide fewer consumer protections against debit fraud. Gas station "skimmers" and long periods of separation from the card at restaurants are some of the more vulnerable spots for use.

AI could be increasing the opportunities for financial fraud

Systems that can reproduce near perfect counterfeits of legitimate financial documents are increasingly prevalent and sophisticated. The international Association of Certified Fraud Examiners estimate organizations lose about 5% of revenue to fraud each year.

Digital re-aging and de-aging of faces in film and TV has become increasingly common

Traditional techniques for accomplishing this process were slow and labor-intensive, and often required manual frame-by-frame edits, forcing them to be reserved for "hero characters" and close-up shots.
