In the past, a bunch of keys hung from your belt, jingling as you walked. Now, a single card in hand covers attendance and access control all in one.
With the convenience of smartphones, even access cards can now be duplicated onto a phone. But for a business, cloned cards create security concerns and chaos \u2014 once an access card can be freely copied, data can easily be stolen, rendering the access control system essentially useless. Yet many businesses still fail to recognize the severity of this problem, leaving them exposed to serious risks of office break-ins and data leaks.<\/span><\/p>

Cloning a single access card takes just 2 seconds\u200b<\/span><\/strong><\/h2>

\u200bMany media outlets have already exposed incidents like this \u2014 you can walk up to any street-side key-cutting stall, without providing any form of ID, pay around NT$100, and have an access card cloned in just 2 seconds. Many lock shops now have card-cloning machines. ID cards and unencrypted IC cards are the easiest to clone, and garage access cards, parking cards, and even elevator cards all carry the risk and hazard of being freely duplicated.<\/span><\/p>

The Encryption Algorithm of Outdated Access Cards Has Been Cracked \u2014 Freely Clonable<\/span><\/strong><\/h2>

Many access control systems in Taiwan still use the MIFARE card's serial number for identification. MIFARE cards were once the most widely used and technologically mature type of contactless smart IC card in the world. However, as far back as 2008, MIFARE's encryption algorithm was cracked, causing a major stir \u2014 the Boston, USA subway system and the London transit system both subsequently suffered hacking attacks, and numerous articles discussing how to crack the MIFARE system key can still be found online today.
Many brands of smartphones commonly used today are capable of cloning MIFARE cards, and video tutorials or tools for copying MIFARE cards can easily be found online as well.<\/span><\/p>

Upgrade to the New-Generation Seos\u00ae Smart Card for Greater Security<\/span><\/strong><\/h2>

\u200bHID Global\u00ae Seos offers outstanding security, with best-in-class encryption technology providing superior protection for your data and privacy, creating an environment that is safer than other credential card technologies and capable of replacing a wide range of traditional and existing credential card technologies.
Compared with traditional credential card technology, Seos provides a higher level of data and privacy protection. This is because Seos uses a layered security approach and strict algorithms to protect data.
Seos, along with its corresponding iCLASS SE\u00ae and multiCLASS\u00ae SE reader platforms, uses a layered security approach that combines multiple mitigating security controls to protect resources and data. One security layer comes from the Secure Identity Object (SIO), an encrypted, protected data model used to store secure identity data (such as a user ID).<\/span><\/p>
