ACR1281U-C1 DualBoost II is the second generation of ACS’s ACR128 DualBoost Reader. It is a dual interface reader that can access any contact and contactless smart cards following the ISO 7816 and ISO 14443 standards. ACR1281U-C1 DualBoost II enables one to integrate conventionally separate and independent applications for contact and contactless technologies into one device and one card. It can be used for online transactions to settle payments securely using credit cards, and it can also be used for topping up contactless cards in automated fare collection systems. It provides the perfect complement to the all-in-one card concept that combines many kinds of smart card applications in just a single card.
The DualBoost Series has PC/SC compliance for both contact and contactless interfaces. It makes use of high-speed communication for contactless cards at a maximum of 848 kbps, which makes it suitable for highly demanding applications. It also provides intelligent support for hybrid and combi cards, such that it detects a contactless card even that has been incorrectly placed in the contact card slot. Lastly, the DualBoost has a built-in SAM slot for added security in both contact and contactless applications.
With additional features such as USB firmware upgradability, contact memory card support and extended APDU support, ACR1281U-C1 DualBoost II is a highly cost-effective, powerful all-in-one device that offers convenience and flexibility to many smart card applications.
