The Hexing CIU EV500 that UMEME is rolling out is a prepaid keypad meter designed for the purposes of prepayment. Its functions include energy measurement, data display, communication, prepayment, UMEME control, keypad input and inquiry, anti-tampering, etc.
Its prepaid mode solves the problem of difficult collection of Yaka fees. It’s based on Standard Transfer Specification (STS), which is an open secure transfer standard and the only international specification on the prepaid system. It has a closed type design which avoids external attack through an open interface. The Hexing Yaka Prepaid meter has an LCD display and keypad input which users will recharge using Tokens they buy.
