iCLASS smart card technology was specifically designed to make access control more powerful, more versatile, and more secure. iCLASS 13.56 MHz read/write contactless smart card technology provides versatile interoperability in applications such as access control, network log-on security, cashless vending, time and attendance, event management and biometric identification. iCLASS smart card technology ensures high security with mutual authentication between smart card and reader, encrypted data transfer, and 64-bit diversified keys for read/write contactless smart card capabilities. Securely separated files enable multiple applications and support future growth. The iCLASS smart card meets ISO standard for card size and thickness for use with direct image and thermal transfer printers. It features a graphics quality surface optimized for Photo ID printing, and is available in standard PVC construction, or a composite polyester/PVC construction for more demanding high wear and tear environments. The smart card can be produced with visual security and anti-counterfeiting features such as holograms, ultra-violet fluorescent inks, micro-printing, or a custom logo to quickly and easily identify genuine smart cards.
