Update old card values

CardValueUpdater.kt

// We have RfidListener interface where you can get callback when a card is punched.
// This class has two methods:
// fun onRfidRead(rfidInfo : String)
// fun onRfidReadWithOldValue(rfidInfo : String, oldRfidInfo: String, useRfidStandardization: Boolean)
// onRfidRead method is used right now to get card value from SDK but due to some reasons such as supporting new card types etc...
// We have to update old card values with new ones using onRfidReadWithOldValue function
// Launcher applications are good place to handle with update process at least we update old values in that application.
// You have to override onRfidReadWithOldValue function in order to update old values and call
// super.onRfidReadWithOldValue function after update process
// I am sharing code snippet from our implementation

override fun onRfidReadWithOldValue(rfidInfo: String, oldRfidInfo: String, useRfidStandardization: Boolean) {
    "onRfidReadWithOldValue new value = $rfidInfo, old value = $oldRfidInfo".log()
    updateCardInfo(rfidInfo, oldRfidInfo)
    super.onRfidReadWithOldValue(rfidInfo, oldRfidInfo, useRfidStandardization)
}

private fun updateCardInfo(rfidInfo: String, oldRfidInfo: String) {
    val employee = RfidCard().getEmployee(rfidInfo)
    // If employee is null which means card value is not updated
    employee?.run {
        val oldRegisteredEmployee: Employee? = RfidCard().getEmployee(oldRfidInfo)
        // We have an employee which has old card value
        if(oldRegisteredEmployee.isNotNull()) {
            RfidCard().getCard(oldRfidInfo)?.apply {
                number = rfidInfo
            }?.update()
        }
    }
