The service requires your registered PosoMoney mobile number and self-activated PIN. Every transaction is effected by SMS and authorised with a PIN. The technology does not store information as it is highly encrypted. In addition, there is only one wallet linked to an account. BotswanaPost has a strict policy on anti-money laundering. In the event that a phone is lost or stolen, money can only be recovered upon replacement of the SIM card and SIM-Skin, which requires the physical presence of the owner and production of an ID.
