Simply go to the Google Play Store to get started. Then download the Google Pay app, follow the instructions on how to upload your ING card details, and start paying with your phone.
Getting started takes no time at all and all you need is your phone, your ING card, and a few minutes.
It's highly secure, as your card details are not sent to the merchant. A virtual account number is sent instead - and your mobile doesn't store card details.
You never leave your phone behind, and with Google Pay, it's all you need to shop - so forget the wallet and lighten the load.
