Octopus card
Meanwhile, ACS was selected to provide ACR122 contactless card readers to Pacific Century CyberWorks Limited (PCCW) Hong Kong in 2008. ACR 122 Octopus card readers were made available to be connected to PCCW's multimedia VoIP phone, thus allowing cardholders to check their card balance and their ten most recent transactions in the Hong Kong Octopus Card without the need for Octopus Enquiry Machines that are located in MTR stations only.
