HID Global has introduced a portable, dongle-sized USB smart card reader that includes a removable MicroSD flash memory slot and reader for subscriber identity module (SIM)-sized contactless smart cards. By supporting flexible memory up to 32GB, the OMNIKEY 6221 USB reader is both cost-effective and a future-proof investment for organizations looking to improve mobile document security. The reader delivers data protection and secure content issuance using encryption and digital signatures in conjunction with PIN protection. The reader is based on the same technology and drivers as HID's OMNIKEY popular desktop product family of logical access readers, making it easy to integrate into existing applications.
