소개
Also known as a chip card or an integrated circuit card (ICC or IC card), the smart card is a physical authorization device shaped like a credit card, and is used to gain access of another device. Smart cards can provide strong security for things like identity, authentication, financial records, etc. The smartcard reader houses the smart card, and can read or write the information on a smart card.
If you find that your device is not properly reading or writing the information on a smart card, it may be time to replace it. Follow these instructions to replace the smartcard reader in the Lenovo ThinkPad T450 laptop.
