How to Tap Contactless Cards / Devices
To tap a contactless card or smartphone, cardholders should:
1)
Wait for the device to display an action prompt.
a)
Devices with a touchscreen show on-screen text and buttons (see
examples).
b)
Devices with or without a touchscreen show the transaction status using the LEDs. LED1 lights
solid green and all other LEDs are off, per EMV standards, to indicate it is ready for a tap (or
swipe or insert, if the host has enabled those interfaces for this transaction).
c)
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
On
and has a payment app configured to process transactions. For details,
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
).
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 a prompt that the device has successfully read the card, smartphone, or other contactless
payment device, then remove it from the contactless landing zone.
a)
The device quickly lights the second LED green to show it is processing, then lights the third
LED green to show it has successfully read the tap, then lights the fourth LED green to show the
read is complete (see
b)
The device beeps once.
c)
Devices with a display show
PROCESSING
, then
REMOVE CARD
, then
THANK YOU
.
d)
The device ends the transaction and reports the transaction status to the host.
5)
If the device can not communicate with the card, smartphone, or other contactless payment device:
a)
The device ends the transaction.
b)
The device lights LED4 red for a short time.
c)
The device beeps twice.
d)
Devices with a display show
INSERT, SWIPE, OR TRY ANOTHER CARD
, then
THANK
YOU
, then return to the idle page (see section
6.4.1Welcome Page / Active Idle Page
).
e)
The device notifies the host that the transaction failed. If this occurs, the host software may
choose to retry the transaction (for example, with different payment types enabled) or revert to
prompting the operator to enter card data manually (see section
.
