The Security Bank app applies these amount rules:

• If you enter PHP 500 or less, the amount will be rounded down to 0.
• If you enter more than PHP 500, the amount will be rounded up to the nearest PHP 1,000.
• If you tap + or –, the amount will adjust in increments of PHP 10,000.
• Only increments from PHP 1,000 to PHP 10,000 are accepted. Other amounts will not be accepted.
