Shop Right Off the Subway Wall With PayPal

Online payment service company PayPal is testing a new mobile shopping initiative that allows consumers to point and purchase using QR codes. PayPal has created catalog "mobile shopping walls" in 15 metro stations in Singapore. The large displays feature Valentine’s Day offers from eight participating retailers. The user will need to first download the PayPal QR code reader app, which scans the barcodes and allows the user to log into PayPal to purchase the items.
