ACR-1281U-S1 DualBoost II Serial Dual Interface Reader


ACR-1281S-C1 DualBoost II Reader

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.
