What is a smart card reader?

A smart card reader is a device used to read data from a smart card, which is a small plastic card containing an embedded chip. The chip in the smart card stores information securely and provides a way to authenticate users and authorize transactions.

Smart card readers come in various forms, including portable USB readers that can be plugged into a computer, stationary readers built into devices like ATMs or POS terminals, and contactless readers that can communicate with a card without the need for physical contact.

These readers are commonly used for a variety of applications, such as accessing secure buildings, making electronic payments, and storing personal information like medical records or loyalty program points.

Most smart card readers are compatible with a range of smart card standards, such as EMV for payment cards, PIV for government-issued identification cards, and SIM cards for mobile phones.

Overall, smart card readers play a crucial role in securing sensitive information and enabling secure transactions in a variety of industries.
