Most people interested in electronic payments have probably read reviews of PayPal's mobile payment system launched in March. However, if you haven't had a chance to use it, by all means head over to PayPal Mobile and activate your phone.

The service covers two mobile payment services:

1. Person-to-person payments: PayPal's email-payments service is extended to phones, mobile or land-line, allowing users to send money to anyone with a phone number using text messaging or by following the prompts on PayPal's toll-free number (800-4PayPal).
2. Text to buy: To buy things at participating merchants, users send the text message a code to the merchant's text-message number; for example, listed on the PayPal site today is a special offer to purchase a DVD Of X-Men 2 from by texting "X2FF" (full-frame) or "X2WS" (widescreen) to 63336 to FoxStore.com.

Sign-up Process
The sign-up process is absolutely painless (click on screenshots below for a closer look). Assuming you already have a PayPal account, just enter your phone number and then a few seconds later answer the verification call on that number. After that, you can send money to any other phone by sending a text message from your phone or calling PayPal's toll-free access number and following the simple prompts to make a payment.

The company ran a sweepstakes during the first month to encourage activation with instant prizes valued up to $1,000 (see screenshot left). The sweepstakes has ended, but not before we bagged a fresh $5 credit to our account. All entrants are also in the running for a new BMW.

Security
Although it will take some convincing before PayPal Mobile hits the mainstream, it's really far more secure than using a credit card. When you text money to someone or to pay for goods and services, PayPal first confirms the purchase by calling your designated phone number for confirmation with a self-selected PIN number. At that time, you are also able to make changes, such as altering the default funding source, which is always bank transfer (see inset for PayPal's how-to-use instructions).

Analysis
In the United States, payment by phone is likely to be a small subset of the "online payments" market. It provides a good solution for situations where a computer is not available (purchasing a new DVD from a magazine ad or paying your friend for the concert ticket she just gave you).

However, in other parts of the world where mobile phone usage is far higher than computer usage, it could become an important payments vehicle.
