...
const CartScreen = () => {
    ...
    const [showPayfast, setShowPayfast] = useState(false)
    ...
    const transactionDetails = {
        itemName:'iPhone',
        amount: 1500.25
    }
    return <View>
    ...
    <PayFast
        merchantId={process.env.PAYFAST_MERCHANT_ID}
        merchantKey={process.env.PAYFAST_MERCHANT_KEY}
        passPhrase={process.env.PAYFAST_SIGNATURE_PHRASE}
        sandbox
        isVisible={showPayfast}
        onClose={() => setShowPayfast(false)}
        transactionDetails={transactionDetails}
      />
    ...
    </View>
}

export default CartScreen

Adding saving a card for future use

Unfortunately Payfast does not return any details for your saved card, except for the token, therefore you can't show the last 4 digits for the user to remember the card they saved, but the update card screen shows the last 4 digits and the expiry date

...
import {PayFastSaveCard} from 'react-native-payfast-checkout'
...
const PaymentOptionsScreen = () => {

    const [showAddCard, setShowAddCard] = useState(false)
    const [showUpdateCard, setShowUpdateCard] = useState(false)

    const transactionDetails = {
        customerFirstName: 'John',
        customerLastName: 'Doe',
        customerEmailAddress: 'name@email.com',
    }

    return <View>
    ...
    <PayFastSaveCard
        transactionDetails={transactionDetails}
        merchantId={process.env.PAYFAST_MERCHANT_ID}
        merchantKey={process.env.PAYFAST_MERCHANT_KEY}
        passPhrase={process.env.PAYFAST_SIGNATURE_PHRASE}
        notifyUrl=''
        isVisible={showAddCard}
        onClose={(isDone) => {
            // Do things here then
            setShowAddCard(false)
        }}
    />
    ...
    <PayFastUpdateCard
        cardToken=''
        isVisible={showUpdateCard}
        sandbox
        onClose={() => {
            // Do things here
            setShowUpdateCard(false)
        }}
    />
    ...
    </View>
}

export default PaymentOptionsScreen

Using a token in a transaction

...
import { usePayFast } from 'react-native-payfast-checkout'
...

const CheckoutScreen = () => {
    ...
    const { chargeCardToken } = usePayFast({
        merchantId:{process.env.PAYFAST_MERCHANT_ID}
        passPhrase:{process.env.PAYFAST_SIGNATURE_PHRASE}
    })
    ...
    const onCheckout = async( ) => {
        try {
            const { message, pf_payment_id } = await chargeCardToken({
                token:'',
                total:10000 // in cents e.g 10000 = R100,
                reference:'',
                itemName:''
            })
        } catch(error){
            console.log({error})
        }
    }
    ...
    return <View>
    ...
        <Button text='Checkout' onPress={() => onCheckout() } />
    ...
    </View>
}

export default CheckoutScreen
