6.6.2 How to Tap Contactless Cards / Devices

To tap a contactless card or smartphone, follow these steps:
1) Check LED status:
a) The device shows the transaction status using the LEDs. LED1 lights solid and all other LEDs
are off, per EMV standards, to indicate it is ready for a tap.
b) All devices report detailed transaction status to the host, and host software may report that
information to operators so they can guide cardholders through the transaction (for example,
"please tap your card now").
2) If the cardholder is using an electronic payment device, such as a smartphone, make sure the payment
device has NFC turned
see the documentation provided by the smartphone manufacturer and payment app publisher.
3) Briefly hold the card, smartphone, or other contactless payment device over the contactless landing
zone, indicated by the EMVCo Contactless Indicator symbol on the device's face (see Figure 6-1).
Because each smartphone model may have its NFC antenna placed differently, the ideal tap position
may vary by make and model. For example, Samsung users may need to center the phone on the
contactless landing zone, while Apple users may need to tap the top of the phone on the contactless
landing zone.
4) Wait for LED status:
a) The device quickly lights the second LED to show it is processing, then lights the third LED to
show it has successfully read the tap, then lights the fourth LED to show the read is complete (see
Figure 6-2).
b) The device beeps once.
c) If the transaction requires a signature, the device sends a notification message to the host that
includes the status Signature Capture Requested. In this case, the solution design collects the
cardholder's signature via a different method.
d) The device ends the transaction and reports the transaction status to the host.
5) If the device cannot communicate with the card, smartphone, or other contactless payment device:
a) The device ends the transaction.
b) The device lights LED4 for a short time.
c) The device beeps twice.
d) The device notifies the host that the transaction failed. If this occurs, the host software may
choose to retry the transaction or revert to prompting the operator to perform another operation
that is specific to the solution design.
