Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core technologies employed?Near Field Communication (NFC) and Radio-Frequency Identification (RFID) enable wireless data exchange
2. What is the standardization framework?The EMV (Europay, Mastercard, and Visa) standard governs secure contactless transaction protocols
3. How does contactless payment keep my money safe?It keeps money safe by using very short-range signals and special codes that are scrambled. Only the right device can read them, so nobody can steal them.
4. Why do we tap a card instead of swiping it?Tapping is faster because the card talks to the cashier’s machine with a tiny signal, so you don’t have to slide or insert it.

Near Field Communication (NFC): A short-range wireless communication technology enabling device-to-device data transfer when in close proximity.
Radio-Frequency Identification (RFID): A technology utilizing radio waves to identify and track tags attached to objects, often used in contactless cards.
Tokenization: A data security process that substitutes sensitive information with non-sensitive equivalents, known as tokens.
Point-of-Sale (POS) Terminal: The hardware device used by a retailer to process card payments during a customer transaction.
