# Check contactless capability

## Overview

Run this check if your **digital wallet application** supports contactless payments.

Call it after **NFC Wallet SDK** initialization, and before [Enroll wallet](/nfc-wallet-sdk-ios/implement-nfc-wallet/enroll-wallet.md) and **Tokenization**.

{% hint style="info" %}
If the device is not eligible for contactless payments, hide or disable contactless payment entry points for the **end user**.
{% endhint %}

## SDK Integration

Use `deviceEligibility` with `contactlessPaymentEligibility`.

Handle these results:

* `supported`: The device can make contactless payments.
* `deviceNotSupported`: The device does not support NFC or HCE.
* `systemNotEligible`: The device or Apple ID is not in the EEA (European Economic Area).
* `iosVersionNotSupported`: The device does not meet the minimum iOS version (iOS 17.4).

```swift
let contactlessEligibility = await TSHPay.shared.deviceEligibility.contactlessPaymentEligibility
            
switch contactlessEligibility {
  case .deviceNotSupported(let reason):
      // Device is not eligible due to missing NFC or HCE support.
      break
  case .systemNotEligible:
      // System is not eligible because the device or Apple ID is not in the EEA.
      break
  case .iosVersionNotSupported(let currentVersion):
      // The OS version does not meet the minimum required version (iOS 17.4).
      break
  case .supported:
      // Device is eligible to make contactless payments.
      break
}
```

{% hint style="info" %}
Run this check before you call [Enroll wallet](/nfc-wallet-sdk-ios/implement-nfc-wallet/enroll-wallet.md) and [Tokenize a card](/nfc-wallet-sdk-ios/implement-nfc-wallet/tokenize-a-card.md).
{% endhint %}
