In the beginning, there was Smart...

When PSR was launched in June 2006, there was only one telco that accepted entries: Smart.

The rules were fairly complex:
1. Text "PSR (space) TIN # of establishment (asterisk) OR # (asterisk) OR Amount" to 9777. The text should not include commas, periods, hyphens or centavos, or this will result in an error. A typical entry, say for the Starbucks Grande Mocha Valencia I just bought, would look like this -
PSR 005215077016*182846*125
2. Each P100 in the receipt amount entitles the texter to one raffle entry, e.g, an OR for P525.00 is entitled to five raffle entries.
3. Minimum OR value is P100. OR amounts are rounded up to determine eligible number of entries (i.e., an OR for P550.00 is entitled to six raffle entries).
4. One text = one raffle entry = P1.50 (i.e., to get all the raffle entries, the texter must text PSR several times).

Despite these hurdles, in the first week of the program, PSR averaged 20,000 entries per day.
