Guide: How to Convert Offline Spend to Online for More Rewards

There are quite a few cards like DBS Woman’s World Mastercard or Citi SMRT that give their bonus earn rates specifically on online spend, but they can still be very useful for in-person spend if you know how to convert offline spending into online transactions.

Here are several ways you can make use of your online spend cards for your in-person spending. Towards the end of the article, there is also a table of popular online cards and their compatibility with these methods.

Buy vouchers online and spend them in stores

One popular way is to buy vouchers online and use them for in-store purchases.

Common platforms that sell vouchers are HeyMax, ShopBack, and Wogi. Voucher purchases on these platforms should code as online transactions, though do note that some cards like HSBC Revolution and UOB Preferred Visa are more MCC-sensitive.

Use Amaze

Instarem Amaze is a wallet app that allows you to add up to 5 different Mastercard credit cards to it, and make payments with the Amaze card. Transactions made on the card are charged to the underlying Mastercard, and such transactions count as online ones.

Unfortunately, it has been nerfed quite a lot over the years, and excluded by quite a few bank. Citi Rewards, however, is a notable card that still works with Amaze, albeit with a 1% fee (with a S$0.50 minimum per transaction) on local transactions. The combo still works great for overseas spend where there is no fee charged, and Amaze’s forex spread of around 2% is lower than the 3.25% Citibank charges.

Pay within apps or websites

Payments through apps count as online transactions, and many physical retailers and restaurants these days accept app payments. Wallet apps like FavePay, Kris+, and ShopBack Pay should be fairly common, and some retailers also have their own app which may allow you to make in-app payments.

Restaurants sometimes also have QR menus where payments can be made, and such transactions will be online.
