What device should be recommended for allowing secure access to company doors by swiping an ID card?

The most suitable device for allowing secure access to company doors by swiping an ID card is a smart card reader.

Smart card readers are specifically designed to interact with smart cards, which are a type of ID card that typically contains embedded integrated circuits capable of processing data. These smart cards often utilize encryption and can carry secure credentials, ensuring that the information stored on them remains protected during transactions.

In contrast, a magstripe reader is designed to read the magnetic stripe found on certain types of cards, primarily debit and credit cards. While some ID cards might have a magstripe for access, they usually do not provide the same level of security as smart cards, which can include stronger authentication methods.

The use of a barcode scanner is primarily intended for reading barcodes, which can be less secure and easier to duplicate or forge compared to the encrypted data used in smart cards. Furthermore, a fingerprint scanner requires biometric authentication and does not utilize ID cards for access control, making it unsuitable for this purpose.

Overall, smart card readers are specifically engineered to securely read the data on ID cards designed for access control systems, making them the best choice for ensuring safe and reliable entry to company premises.
