Text fields can be formatted in 3 different ways:
- Alignment (left, right, center and natural)
- Date formatters (date and time display styles, like 9/12/2012 or Sep 12, 2012)
- Number formatters (decimals, percentages and currencies)
The advantage of specifying a format is that the content will be displayed in a format familiar to the device user.
E.g. the number 'One Thousand' would be displayed as 1,000 to a US user, as 1'000 to a German user and as 1 000 to a French user.
One disadvantage, particularly with date formats is that some language formats are longer than others which may cause unexpected results when the pass is installed on a 'Foreign' device.
