PC-Linked Smart Card Readers with Mass Storage
A smart card reader and a flash drive in one USB device.
A mass-storage smart card reader plugs into a computer like a USB drive, reads a SIM-sized smart card, and stores data or software in built-in flash memory. ACS lists the ACR100I SIMFlash II in this category; BSD Infotech can confirm availability for your requirement.

What Is a Smart Card Reader with Mass Storage?
Smart Card and Storage in One Device
Smart card reader
A SIM-sized smart card sits inside the device, for applications that need the card’s keys or data.
Flash storage
Built-in flash memory holds data or portable applications, like a USB drive.
One USB connection
ACS describes the ACR100I as a USB combo device: a smart card reader and a mass-storage device over one USB 2.0 connection.

ACR100 SIMFlash (ACR100F / ACR100H)
The earlier SIMFlash readers combined contact smart card technology and mass storage in a single USB device. ACS lists the ACR100F (CCID) and ACR100H (HID) as end of life. See the ACR100 SIMFlash (CCID) and ACR100 SDK pages.

SIM-Sized Card Support and Flash Storage
SIMFlash readers take a SIM-sized (plug-in) smart card, which stays inside the device, so the reader is as portable as a USB drive. On the ACR100I, the flash memory can be arranged as up to three drives, from these types: a private or security area, a public area, a CD-ROM/auto-run area, and a hidden area. That arrangement lets one device carry, for example, a portable application alongside protected data.
PC/SC and CCID
The earlier ACR100 SIMFlash (CCID) was PC/SC compliant; ACS also made an HID version. For the ACR100I SIMFlash II, confirm PC/SC, CCID and driver support for your operating system with BSD Infotech before ordering. Our Smart Card Reader SDK and Integration page explains PC/SC and CCID.
Applications
Applications listed for ACS SIMFlash readers include:
These are manufacturer-listed uses, not BSD project references.
SDK and Software Integration
ACS made SDKs for the earlier ACR100 SIMFlash readers, including sample code and a demo program; see the ACR100 SDK page. For the ACR100I, ask BSD Infotech about the current SDK and integration support.
