: The chip can require a 4-digit PIN for authentication (similar to a debit card) or a signature, providing varying layers of identity protection.
Payment cards use an embedded microprocessing chip, often called , to provide several security features: : The chip can require a 4-digit PIN
: Unlike magnetic stripes, the chip generates a unique transaction code (cryptogram) for every purchase, making it nearly impossible to replicate stolen data for future fraud. increasing processing power and efficiency.
: A critical specification measured in nanometers (nm) , such as 32nm or 5nm. It describes the size of transistor elements; smaller feature sizes allow for more transistors on a single chip, increasing processing power and efficiency. : The chip can require a 4-digit PIN
