Design Specifications

The ReadyPay is integrated into the ReadySet solar charged battery kit. To operate the system customers pay a deposit and receive the ReadySet Solar Power System. They make payment installments via MTN Mobile Money to access power via a unique SMS code on their phone. The code is entered into the ReadyPay Solar Power System and unlock the power flow. After the customer completes their installment payments (usually after 18 months), they receive a code that permanently unlocks their ReadyPay Solar Power System. After that they can use it as much as needed for free. The battery kit itself can be charged by wall outlet, solar panel, or modified to be charged by a user's own power generating device. The basic kit comes with: • 3 Ultra bright LED lights • 2 Phone charging cables • One of two solar panels capable of producing 10 watts or 17watts. The system is capable of supporting daily use of up to: 3 lights for 4 hours and charging 2 phones. Additional solar panels can be purchased and added to the system in parallel to produce up to 75 watts with a total of 5 solar panels. The Fenix solar panels are designed for easy plugin to the battery system. The ReadySet is 8.9”L x 7.2”W x 3.7”H and weighs 2.2 lbs. The solar panel is 17”L x 11”W x 0.9”H and weighs 3.8 lbs. The battery stores 40 Wh of energy.

    MyChild Card consists of a standard booklet which is given to a newborn’s family which assigns them a unique child ID. This acts as a paper version of the child’s health records. The outcome of each visit (vaccinations, check ups etc) are recorded here and a single card is torn off and kept by the health worker. Periodically the cards are collected and taken to be scanned and a central database is updated with the results.

    The benefits here are clear: data entry can be automated leaving skilled health workers with a lower administrative burden, large and unwieldy health records can be safely stored elsewhere.

    A few open questions are:

    How is the local clinic’s information updated? Without the paper records they are limited to the copy that the family looks after which could easily be lost. This could potentially be addressed if those that periodically fetch the new cards to be scanned can return with a (password protected or encrypted) copy of the records to update the offline database in the clinic.

    How secure are the cards? Since the child is referred to by a unique ID, no immediately identifying information need be recorded. However, since sensitive information e.g. HIV status is recorded, great care must be taken to avoid any possible reidentification risk of a child from anonymise information.
