How does the Mastercard Identity Check work if I don’t have a mobile phone or signal?
If mobile verification is not an option, for example you don’t have a mobile phone, or you don’t have any phone reception where you are, you’ll have an alternative option that will allow you to call us on a land line. Our phone lines relating to these calls are open 24/7. We estimate that the majority of transactions will not be affected by this industry-wide change, which is designed to make your online card transactions more secure.
Mastercard® Identity Check™ is only for online transactions, like shopping online. It doesn’t apply to point of sale transactions, such as using a chip and pin or contactless payments.
