Result.success(cardData)\n        } catch (e: NfcException) {\n            Result.failure(e)\n        } catch (e: SecurityException) {\n            Result.failure(e)\n        }\n    }\n\n    // Callback-based approach\n    fun readIdCard(callback: (Result\u003cIdCardData\u003e) -\u003e Unit) {\n        reader.readVietnamIdCard(object : CardReadCallback\u003cIdCardData\u003e {\n            override fun onSuccess(data: IdCardData) {\n                callback(Result.success(data))\n            }\n\n            override fun onError(error: Exception) {\n                callback(Result.failure(error))\n            }\n        })\n    }\n}\n```\n\n### Credit Card Processing\n\n```kotlin\nclass CreditCardProcessor {\n    private val reader =
