Components of E-TopUp and E-Voucher Platform

1. PIN-less Top Up Solution for single & multi-operator

Our technology enables operators of Prepaid Services to offer voucher-less recharge, with no PINs & no restrictions on denominations.

The e-Top up service can be operated either by:

  • The Prepaid Operator themselves for recharge of their service, or,
  • A 3rd party Service Provider who distributes service recharge of either a single or multiple operators under a distribution agreement with them.

The platform supports prepaid services recharge for multiple prepaid services such as mobile, internet, TV, toll, prepaid electricity, etc.), via both models - B2B (distribution via a hierarchical network of agents), or self service recharge (B2C).

Our B2C module enables subscribers of prepaid services to recharge their own or another prepaid account using a m-App, web portal or Kiosk, and making payment via any mode of e-payment (cards, direct bank debit, m-Wallet account, gift cards, loyalty points…).

This platform can be easily upgraded to offer bill payment services using the same IT infrastructure, and same network of agents (B2B model) or via additional tabs in B2C model; this enables service providers to earn additional revenues using their investment in the Estel Prepaid Recharge platform.

Benefits of Electronic Top Up (eTopUp):

  • No PINs, thus no restrictions on recharge denomination; any value recharge!
  • Implementation of e-Top Up solution eliminates use of scratch cards and their risks & costs
  • Merchants selling prepaid mobile recharge purchase airtime value (not PINs), reducing ‘stock out risk’ for fast moving items
  • No risk of theft or damage to stock, as merchant inventory sits in a m-wallet on server
  • Retailers use their mobile phones to buy & sell airtime top up anytime, anywhere

2. Single & Multi Operator e-Voucher Solution

In some countries, Voucher based recharge is a preferred way to recharge prepaid services.

Our e-Voucher technology enables service providers to distribute e-PINs via their merchants, using multiple devices to either print the e-PIN at the point of sale, or, send the e-PIN by SMS to the customer. This potential outsourcing of e-voucher distribution to service providers opens up new & exciting opportunities for them, who can distribute e-Vouchers of multiple services & operators on the same infrastructure, to earn additional revenues.

Our e-Voucher system easily upgrades to full eTopUp enabling operators of Prepaid Services to offer voucher less recharge, with no PINs & no restrictions on denominations.

Benefits of e-Voucher

  • Service Operators need not print scratch cards & incur logistics for distribution, saving significant cost
  • Service Operators can track all e-PIN recharge sales to the last distribution point
  • Our e-Voucher solution reduces fraud and fake, lost, damaged, and stolen vouchers

Service providers can offer a comprehensive bill presentment & payment service for:

  • Multiple billers
  • In either or both, B2C (self payment), or B2B (distribution via a hierarchical network of agents) mode
  • In B2B mode, agents can utilize their ‘common’ working capital (wallet balance) to sell both prepaid recharge & bill payment services

What is an eTopUp (E-Top Up) platform?

An e-top up Platform is enabler of an essential digital service that allows customers to conveniently add credit or data to your prepaid mobile phone without the need for physical scratch cards. Every time when you added balance or credit to your phone number, you essentially went through a eTop Up platform. At times Customers recharge their prepaid accounts or pay postpaid bills instantly by paying cash over the counter to agents paying with any form of e-money (bank, cards or wallets).

This is accomplished through integration with operator IN and/or Billing platforms and transactions requested over various digital channels such as web portals, mobile applications, SMS, USSD, STK, ATM, Mobile Banking etc, and with payment gateways to collect e-money. 

These platforms are deployed by telecom operators to streamline the recharge process, making it easier, faster, and more convenient for both the operators and their subscribers. The platform is especially useful in developing countries where a significant chunk of mobile user base is from the prepaid segment.
