Device Overview
This chapter provides an overview of the e235 device:
The e235 device is a standalone, mobile wireless handheld payment device, making it easy to process contact and contactless transactions anywhere. It provides mobile payment capabilities via 4G connectivity. It is also a powerful 4G/Bluetooth/Wi-Fi (Wireless Fidelity) dual-band solution featuring advanced communication for a few dropped transactions so merchants can accept payments securely, extending their point-of-sale opportunities.
The e235 with physical keypad design accepts all payment methods Magnetic Stripe Reader (MSR), Primary Smart Card Reader (PSCR), Contactless (CTLS), and Wallets. The easy-to-read color screen is fully supported by Verifone's developer toolkit which enables to transform ideas into applications.
