# TKTLVRecord

The base class encapsulating a Tag-Length-Value record.

## Declaration

```swift
class TKTLVRecord
```

## Overview

Overview The CryptoTokenKit framework provides the following concrete subclasses for various TLV record encodings: TKBERTLVRecord for BER-TLV encoding rules TKSimpleTLVRecord for Simple-TLV encoding according to ISO 7816-4 TKCompactTLVRecord for Compact-TLV encoding according to ISO 7816-4
