This section contains a step-by-step guide to creating an application that captures a single field which conforms to a certain regular expression. This could be a date, some code, etc. The more specific the data is, the easier it would be to capture it. In this guide we will capture an alphanumeric code, for example: 69KL46D7WF2AR5U. Code format is the following: it contains 15 characters that are either digits or capital letters, and the first two characters are always digits.
