Acoustic Debit Card for Africa

Categories: Sub-Saharan Africa, Cameroon, Economics & Business, Technology

Olivier Gabirault writes [1] [Fr] about Maâtcard [2], an acoustic, prepayed debit card for developing countries which will debut in Cameroon next April. The Maâtcard functions like a normal credit card, but also emits a unique, unfalsifiable sound, enabling users to securely make payments, buy air time, or transfer funds by telephone.
