This Say It Smart type handles the reading of a credit card number. Any 13, 14, 15, or 16 digit number will be handled. Many times, a credit card number may appear with dashes at certain places in the number. To avoid having to process the data before it is sent to the plug-in, it will understand the credit card number with these optional dashes, though no punctuation other than dashes is allowed. The plug-in reads the credit card number back digit-by-digit, inserting 150 millisecond pauses at certain places where the credit card number is normally divided.
The plug-in Java class can easily be extended to create, in just a few lines of code, a new plug-in performing the same function with a different pause length or additional formatting options.
