Acer has taken a 15.6 percent stake in PChomePay, a Taiwanese internet trading and transactions business.
PChomePay was established in March 2012, focusing mainly on third party payment platforms for online trading.
Acer chairman Stan Shih said: "Acer is going beyond hardware-based thinking with our investment in ecommerce and our self-built cloud. I firmly believe that the cooperation between Acer and PChome Group will gradually produce win-win results."
He added: "Starting off as the technology partner of PChomePay's ecommerce payment gateway, it's possible for Acer to then become the security technology partner of PChome Group. In the long term, our two companies may also collaborate to deliver innovative applications via the 'hardware plus software plus services model'."
Acer entered what it calls the eservice business more than 10 years ago, and today provides secure 24x7 online payment services to banks, traditional retailers and emerchants. In addition, Acer provides a platform for utility payments via banks with "check and pay" services.
Acer says it also provides information security services to 250 "large-scale customers".
