Google AdSense launched the Western Union Quick Cash payments in following four countries in Africa!: Algeria, Ghana, Kenya, and Uganda. "Western Union Quick Cash payments will reach you faster than checks, and they're free of charge. Payments will continue to follow our normal payment schedule and will be available for pickup in your local currency at your local Western Union agent the day after they're issued," stated Google.
A couple of things to note: "We can send Western Union payments only to publishers who've an individual account at this time. Also, the payee name on your account must exactly match the government-issued ID card that you'll use when picking up your payments."
