According to the International Energy Agency, about 30% of african population have access to electricity in 2014. Whithout electricity, people use solutions like kerosene and candles which are risky and costly. Solar kit is secure, environmentally friendly and the best solution for off-grid population. However, the kits cost is a barrier to the population because of their low income. It is therefore necessary, to set up the payment mechanism Pay As You Go (PAYGO), which takes into account the financial resources of the population in order to facilitate the kits acquisition. PAYGO allows the customer to repay progressively and remotely, the total kit price through a series of payments (weekly, or monthly...) according to his resources. A PAYGO platform uses an electronic system to guarantee the payments. This system locks the kit when the payment is not made and unlocks it when the payment is done by the customer. In our work, we designed this embedded system that will compel the customer to the payments in order to repay the kit cost. The system contains a software part where the operation has been programmed and a hardware part where the components we have chosen react to perform the functions. To ensure the secure transmission of information from the producer to the kit through the customer, we used cryptography and we implemented a symmetric algorithm in the embedded system. We have designed a solution very cheap which performs very well the assigned functions.
