II. 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 82.5 mm x 21.3 mm x 9.4 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.
Combi card
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.
