MRM membership app — digital membership cards, stamps and coupons

What is a mobile membership app?

A membership app combines physical membership cards, paper stamp cards, coupons and promotional leaflets on customers' phones. Merchants update news and offers in the administration system, while members view, use and redeem them in the app.

Unlike a social media page, the app's content and member list are managed by the merchant without reliance on a platform algorithm. For SMEs building repeat custom, it is a long-term brand asset.

Five key MRM membership app features

1. Company news and branch information

Publish new products, seasonal items, holiday hours and event news, and list each branch's address, phone and opening hours. Multi-branch businesses can manage information centrally so customers need not search elsewhere.

2. Digital membership cards

Replace physical cards with phones so customers need not remember a card and merchants save printing costs. Staff can quickly identify members and offer member prices or benefits.

3. Latest member promotions

Offer member days, birthday-month benefits and new-member gifts directly to your members, making membership worthwhile.

4. Digital coupons and limited-time offers

Encourage spending at selected times with weekday afternoon-tea coupons, low-season discounts or new-product tastings. Set expiry dates and usage limits more easily than with paper coupons.

5. Digital stamps

Schemes such as collecting ten stamps for a free coffee encourage repeat visits in food service and retail. App-based stamps cannot be lost like paper cards, help reduce forgery and allow merchants to change targets and rewards.

Benefits of a membership app

  • Build your brand: A dedicated app keeps your brand visible on customers' phones
  • Encourage return visits: Stamps, member offers and limited-time promotions give customers a reason to return
  • Reach members directly: Send offers to your member community with less reliance on paid advertising
  • Save printing costs: Replace paper membership cards, stamp cards, coupons and leaflets
  • Update flexibly: Manage information and offers through the administration system
  • Respond to seasonal demand: Use offers to boost quiet periods and new products to increase spend in peak seasons

Paper stamp cards vs social media vs membership apps

Membership promotion methods compared
Comparison Paper stamp cards Social media pages Mobile membership app
What customers carry Easy to lose or forget Nothing to carry Stored in a phone app
Reaching members Only when the customer visits Subject to platform algorithms Publish information and offers directly through the app
Fraud prevention Stamps can be copied Not applicable System records issuance and redemption
Member records No records Follower data only Manage members and campaigns in the administration system
Brand presentation Traditional Displayed alongside other brands Your own dedicated branded app
Content updates Requires reprinting Publish instantly Update through the administration system at any time

Ideally these approaches complement each other: social media attracts new customers, and the app retains existing ones. Promote app downloads in-store through digital displays and Biz Wi-Fi login pages to reach visiting customers.
