HP is working on phones and tablets with built-in near-field communication (NFC) technology for mobile payments, Bloomberg reported on Monday. Much like Google Wallet, which will soon launch for the Nexus S and eventually other Android devices, HP hopes its customers will be able to use the company’s products to make mobile purchases in retail outlets. Similarly, HP has a plan to create an entire ecosystem where users will be able to to receive coupons or other benefits, such as loyalty points, from NFC-enabled advertisements. While sources told Bloomberg the products could launch by year-end, HP hasn’t been known to deliver new mobile devices to the market very quickly in the past. It’s also still unclear who the company’s mobile payment partners will be.
