Paper card, app or Wallet Card: which is best for you?

The app column draws on what those sixteen programs publish. The Wallet Card column describes native.cards.

The field study these Articles lean on most was run on a paper card. Published in 2006, it tracked the customers of a café on an American university campus, who carried a card: ten coffees, one stamp a visit, then a free one. Customers bought faster as the card filled, "an average acceleration of 20%" between the first gap and the last (see How soon should customers earn their first reward?).

The same paper shows what it took to learn anything from the cards. The stamps came from numbering machines that, "unbeknownst to customers", gave each one a serial number, so that purchases could be tracked. Members were asked to write a name and email address on the back, so that two cards could be matched to one person. Even so, the authors write, the design "enabled us to collect only those cards that were completed and redeemed for a reward". To see the customers who had given up, research assistants bought unfinished cards back for US$4 each and a 1% chance of US$100. They acquired 73, which had been in circulation for 65 days on average, against about 25 for the 949 finished ones.

An owner has none of those tools. With paper you know how many cards you printed and how many came back full. You do not know who holds the rest, whether they still come, or who stamped what. You cannot tell anyone that a free coffee is waiting. That was one café on one campus, but paper has the same blind spot anywhere.

Paper also does some things better. It needs no phone, no signal and no email address, and joining takes as long as handing the card over. It works in a basement food court and for the regular with a basic phone. And it leaves you with no list of personal details to look after.

On 10 October 2026 we opened the published pages or App Store listings of sixteen large programs in Malaysia, from Tealive and ZUS Coffee to Lotus's, Watsons and GSC. Every one has its own app. On the pages we read, at least two describe no other way to join: Tealive's FAQ says "When you download & register the Tealive App, you will automatically become a member", and FamilyMart's terms describe sign-up through its mobile app.

For the customer the first step is a download. The eight iPhone apps whose listings we read ran from 28.5 MB (iAEON) to 207.7 MB (Watsons MY), and five were over 120 MB. We found no sound published figure for how many people give up between a counter and a finished registration.

Large programs can ask for a download because their apps do more than count points. Starbucks Malaysia's listing describes topping up "your Starbucks e-wallet" for payments in store. A customer who orders or pays through an app has a reason to keep it.

For the business, an app is software to build for at least two stores and to keep working as phones change. We found no sound figure for what that costs a small business either. And a customer who installs the app is not yet one you can reach. Airship, which sells notification software to app makers, puts the median share of users who allowed notifications, across its customers' apps in 2025, at 53.3% on Android and 48.85% on iOS. That is a vendor's figure about apps, and nothing like it is published for Wallet Cards.

So build an app when customers will order or pay in it, and add loyalty to that. If points are all it would hold, a card does that job without the download.

A Wallet Card is a membership card kept in Apple Wallet or Google Wallet (see What is a Wallet Card, and how does it work?). Three facts about phones in Malaysia support it, and each has a limit.

Scanning at a counter is already a habit. Bank Negara Malaysia reports that "DuitNow QR transaction volume doubled to three billion in 2025 (2024: 1.5 billion)", across "almost three million registered DuitNow QR touchpoints", a majority of them small businesses. Those are payments and say nothing about sign-ups. They do show that nobody needs teaching to point a phone at a code beside a counter.

Both Wallets matter. StatCounter put Android at about 55% and iOS at about 45% of mobile web use in Malaysia in September 2026. It counts page views on websites that carry its tracker, which is not a count of phones, and a year earlier the same measure read 65% and 35%. Take from it only that a card in one Wallet would miss many of your customers. In native.cards one design produces the card for both.

Not every phone qualifies. Apple says its Wallet app "lives right on your iPhone". Google's help page, titled "Download the Google Wallet app", says "Users need Android 9 to download and use the app", with up-to-date Google Play services. An older Android phone, or one without those services, cannot run it. At least six of the sixteen (GSC, Padini, Sunway, Setel, BonusLink and AEON) also offer an app through Huawei's AppGallery. A Wallet Card has no third route.

The card also does less than an app. Apple and Google set its layout. It takes no orders and no payments, and it holds no money.

The customer scans your QR sign, which opens your Business page, and taps the button to join. They enter an email address and whatever else you chose to ask, tick "I accept the Terms and have read the Privacy notice.", and type the 6-digit code that arrives by email. The page answers "You’re in." and offers the card to their Wallet. There is no app of yours to install and no password, and you do not need Apple or Google developer accounts.

The setup form warns you about asking for more: "Every extra question loses a few people. Email is always asked, so a member can sign in and get a lost card back." Its second sentence covers a lost phone, which paper cannot.

At the counter, staff open the Scanner and scan the card, or choose ID or phone, type what the customer says and read the name back before pressing Yes, continue. They enter the amount if the program earns Points, then their own Staff PIN, then Record purchase. That is slower than a stamp, and it needs a connection: without one the screen reads "You’re offline. Card actions are paused until the connection returns."

In return, each purchase belongs to a member and to the colleague who entered it. Activity History shows Recorded twice in 15 minutes: "Sometimes a genuine second purchase, sometimes a duplicate or a favour at the counter".

Customers then lists everyone who has joined, by how recently they visited. That list is personal data, which brings duties: see Your members' personal data: what the law expects. Notifications go to Everyone, New members or Members with a reward waiting. Offers reach only members who agreed to them, and a card receives at most three notifications in 24 hours. On cost: Zero notification fees.

Two cases are awkward. A member can join and never add the card. They are still a member, and staff can find them by typing their phone number, if your join form asked for one. But Customers marks them No card and no notification reaches them. Home raises it when fewer than 60% of at least twenty members hold the card. And a customer with no smartphone has no way to join at your counter. If that describes many of your regulars, it is the best argument for paper.
