2.2.8 ACR38DT DualKey
Due to the rising demand of e-working methods (remote office, home
office...) and snowballing hacking likeliness, it is the time to properly
secure access to PCs, desktops, Intranet & Extranet networks and
physical access control. ACR38DT offers both solutions based on
SIM-sized combi smart card (contactless and contact card) for
logical and physical access control.
The ACR38DT Contactless/Contact DualKey is an extension of
ACR38T SIMTracker II. It has full ACR38T functionalities with
contactless value-added feature.
i) Serves as a plug-in (SIM-sized) card reader:
It is an extremely compact USB full speed device completely
compatible with the ACR38 smart card reader and is designed to
access SIM-sized smart cards (Plug-in card). With a size of only
78.73 mm x 21.50 mm x 11.00 mm, the ACR38DT is highly suitable for portable applications, as it plugs into the USB
port and requires no additional cable or wiring. It also fulfils the GSM 11.11 specification. It is designed for PC
environment, ultimate smart card peripheral for a PC.
ii) Serves as a contactless card:
While the ACR38DT serves as a contactless card, the embedded antenna coil enables the contactless part of the SIM-
sized combi card to work as a contactless card to communicate with contactless readers.
ACR38DT DualKey is a good quality, reliable and effective reader with designs focusing on convenient use and harmony
with other PC peripherals in terms of shapes and colors. It is ideal for electronic commerce, physical access control,
home banking or e-purse facilities, secure computer access, transportation and GSM application tool.
