Customize generation

createCardPins() method takes an optional options argument

This is the default options interface

const defaultOptions = {
  pinLength: 12, 
  serialNumLength: 15,
  prefixCharacters: '',
  numberRequired: 20
}

So you can do something like this

const serialPinPairs = await createCardPins({
  pinLength: 10,
  serialNumLength: 16
  prefixCharacters: 'GH',
  numberRequired: 1
})

console.log(serialPinPairs)

[
   { pin: 1501856528, serial_num: 'GH7596177621600189' },
]

Note that the createCardPins() method is always returns an array of SerialPinPair interface
