MobiBucks offers a new way to purchase items in stores that involves no cash, no credit cards, and apparently, no hassle. Instead of traditional payment methods, MobiBucks lets you pay for your purchases using only your mobile phone number and a 4-digit PIN. To use MobiBucks, you'll need to register for the service online or at a participating store (don't worry, it's free). Then, add money to your account using cash, credit card, or transfer from your bank account (you can do this online or in the store itself). The merchant will enter in your mobile number and PIN into the MobiBucks machine, and you will immediately receive an SMS text message confirming the transaction. Additionally, you can manage your MobiBucks account online to keep track of your withdrawals and deposits.
