Delegate<\/h2>\n

The transactionRequiresSignature<\/code> delegate is called when a signature must be confirmed as part of processing a transaction. Handle the\u00a0transactionRequiresSignature<\/code> delegate by writing the POS app to call either\u00a0[ADYSignatureRequest submitConfirmedSignature:]<\/code>\u00a0or\u00a0[ADYSignatureRequest submitUnconfirmedSignature:]<\/code>.<\/p>\n

After this method has been called, the transaction will be paused until either\u00a0submitConfirmedSignature:<\/code>\u00a0or\u00a0submitUnconfirmedSignature:<\/code>\u00a0has been called on the given\u00a0signatureRequest<\/code>.<\/p>\n

This method must be implemented in two different ways, depending on the presence of a printer on the payment-device (as determined by the\u00a0paymentDeviceHasPrinter<\/code>\u00a0method on the Adyen class).<\/p>\n

If the device has a printer:<\/p>\n

    \n
  1. The device prints a receipt, which must be signed by the customer.<\/li>\n
  2. The attendant compares this signature to the signature on the card, and either confirm that they are identical, or not.<\/li>\n
  3. Implement the method to show a user-interface where the attendant can choose between\u00a0Confirmed\u00a0or\u00a0Not confirmed, for example by pressing a button.<\/li>\n
  4. The method must call either\u00a0submitConfirmedSignature:<\/code>\u00a0or\u00a0submitUnconfirmedSignature:<\/code>\u00a0on the\u00a0signatureRequest<\/code>, both with\u00a0nil<\/code>\u00a0as the\u00a0signatureImage<\/code>\u00a0parameter, to continue transaction processing.<\/li>\n<\/ol>\n

    If the device does not have a printer:<\/p>\n

      \n
    1. Implement the method to display a user-interface on which the customer can draw a signature.<\/li>\n
    2. Implement the method to allow the attendant to confirm or deny the drawn signature after comparing it to the signature on the card - for example, by pressing a button.<\/li>\n
    3. The method must call either\u00a0submitConfirmedSignature:<\/code>\u00a0or\u00a0submitUnconfirmedSignature:<\/code>\u00a0on the given\u00a0signatureRequest<\/code>, both with the drawn image as\u00a0signatureImage<\/code>\u00a0parameter. <\/li>\n<\/ol>\n
      \n

      Instead of calling\u00a0submitConfirmedSignature:<\/code>\u00a0or\u00a0submitUnconfirmedSignature:<\/code>, it is also possible to cancel the transaction at this point as usual, by calling\u00a0[ADYTransactionRequest requestCancel]<\/code>. After a transaction has been cancelled, subsequent calls to\u00a0submitConfirmedSignature:<\/code>\u00a0or\u00a0submitUnconfirmedSignature:<\/code>\u00a0will have no effect.<\/p>\n<\/div><\/div>\n
