Recharge Architecture

How Vensora Prepaid Metering Operates

Understand how STS token and IC card systems manage credit replenishment, valve operation, and load control with zero estimated billing.

01

Purchase credit remotely via mobile or retail

Buy water or electricity units through supported mobile banking apps, digital wallets, USSD codes, online utility portals, or authorized retail kiosks.

02

Receive your 20-digit encrypted token

A unique 20-digit cryptographic STS token is issued and delivered via SMS, app receipt, or printed voucher. The token securely encodes your purchased units specifically for your meter serial number.

03

Enter the code on your keypad or indoor CIU

Type the 20-digit code directly into the meter's integrated numeric keypad (water meter) or indoor Customer Interface Unit keypad (electricity split meter). No wireless network is required at the meter during token entry.

04

Balance updates & automated supply

The meter validates the token locally and updates your credit balance. The motorized valve or internal electrical relay maintains supply; it restricts flow or disconnects power automatically if credit reaches zero.

STS Token Recharge

Input via 12-key meter keypad or indoor CIU

Specification Note

Important Distinction: Purchasing credit on a mobile phone generates an encrypted 20-digit token. The credit is transferred to the meter by entering this token on the keypad — there is no automatic over-the-air wireless credit injection without a specialized AMI network.
