The PAX S300 is a compact, customer-facing integrated retail PIN pad built for semi-integrated checkout lanes in retail and hospitality. It pairs a 3.5" (240×320) color LCD touchscreen (for on-screen prompts and e-signature) with EMV chip & PIN, NFC/contactless, and magstripe acceptance, and is designed around strong transaction security including PCI PTS 4.x with SRED. Connectivity is primarily wired, using a single multi-function cable port that supports Ethernet (LAN), USB device, and RS232 (cable/configuration dependent).
