POS Terminal
Last Updated: Oct 4, 2024

Point of Sale (PoS) terminals are key elements in payment systems for retailers or restaurants
in Smart Cities. These battery-powered terminals have small form factors and can integrate
functions such as a display, a card reader, a keypad and a printer. Terminals usually include
wireless communication to a back-office server or a main stationary ePOS terminal. They also
support magnetic, smart and contactless payment cards.
NXP solutions power secure, on-the-go mobile payment terminals, providing end users theease-of-use of contact and contactless payment. Our security features help the designer to get
the necessary PCI PTS PIN entry device (PED) and EMVCo certifications.
