Azteco, The easiest way to buy Bitcoins. Redeem Your Azteco Bitcoin Voucher. Azteco makes getting Bitcoin very simple. We use a voucher system that people are already familiar with to deliver Bitcoin to any Bitcoin address in seventy seconds or less. The process is exactly the same as topping up a "Pay as You Go" mobile phone account. Go to one of our outlets, pay by Credit Card or Cash, receive your Azteco Voucher immediately. You then redeem your voucher at the Azteco website to any Bitcoin address. Our system does not require manufacturing custom vendor terminals; any consumer grade laptop and printer can act as a vendor's Azteco terminal, and vendor accounts can be set up in minutes. It only takes four clicks to issue our vouchers.
