Take your business anywhere with the POSket by PAX app, a mobile point of sale solution that fits in your pocket. When paired with a supported PAX device*, the POSket app turns your Apple iPhone and/or iPad into a secure, easy to use payment solution that will accept chip, contactless, and mag-stripe credit card transactions as well as cash. The POSket app also offers inventory control, transaction reporting, customized tax rates, and full transaction support through the Uptrillion Merchant Portal (Uptrillion Account required). *Devices currently supported include the D135, but other devices are coming soon and will be added here.
