How to use

1. The user clicks 'Ir a Pagar'
2. Enter the data:

• Número de tarjeta: Accepts between 12 to 19 numbers without spaces
• MM: Select card expiration month
• YYYY: Select card expiration year
• CVV: Enter cvv
• Primer Nombre: Accept only one name and no spaces
• Primer Apellido: Accept only one last name and no spaces
• Correo electrónico: Enter a email

3. Wait 2 seconds aprox. while the next screen loads
4. Finally it will show you if the card is valid or not

** OBS: This simple application is a payment simulation, so if the card is valid, it will indicate a transaction code, but it is only so as not to lose the context
