What are referral cards?   

Referral cars are similar to business cards your customers can carry around if they want to talk about your business to friends and family. They talk about incentives like cash, discounts, free services, or gift cards. Based on your choice of marketing channels, referral cards can be physical or digital.

People love to share their experiences about businesses with others, good and bad. And businesses today are capitalizing on that need to share by incorporating rewards programs and referral cards. 

Leveraging referral cards also promotes brand awareness. The more people see your business’ branding and hear of positive experiences, the more likely they are to patronize and recommend the business. 

Referral cards are an effective tool that allows your company to capitalize on great customer service experiences and drive new business.

Example of a referral card

How do referral cards work?

Referral cards are quite simplistic in their function. All you have to do is ensure that your customers can share them easily via physical or digital mediums. 

You can hand out referral cards 

  • After a customer has made a purchase 
  • Shared a positive review 
  • Visited your store 
  • As part of your mass lead generation campaigns such as flyer distribution, mail campaigns, and so on. 

The referral card carries your business name and a description of the incentive the customer can claim if they share the business with a friend or family member. 

The incentive motivates your existing customers to share these cards with people they know, especially if they like the product or service.

How to make a referral card? 

While physical cards have their place, sophisticated multi-location brands use local intelligence to make their referral programs smarter. By leveraging a unified CDP, you can identify your most loyal customers—those with high sentiment and repeat purchase history—and trigger automated, personalized referral invites via the Referral Agent at the exact moment they are most likely to advocate for your brand. 

On your referral card:

  • Share the details of your business so customers know about your products during the referral process. Always make sure to include your contact details.
  • Offer a brief description of your program. Share what the existing customer and the prospective customer gets when they use the referral card.

Most importantly, keep it simple and make it easy for your customers to participate.

You don’t want your referral program to be complicated or hard to take advantage of. 

Read on to find some of the best referral card examples below. Use these as inspiration to develop your own and come up with rewarding referral card ideas.

8 best referral card ideas for your business

Referral business cards

Example how business cards can be used as referral cards

Business cards usually get tossed in a drawer, or worse, directly into the recycle bin. But a referral business card is another matter entirely. When you assign new value to your traditional company business cards by making them referral cards, you incentivize customers to hold on to them.  

Business cards turned into referral cards serve two purposes. 

  • They share your business information with your customers.  
  • They offer an incentive for referring a friend. 

The front of the card works best for relevant business information, while the back of the card can outline the details of the referral program.

Referral postcards

Example of a referral postcard

Postcards are great tools for sharing your referral program as they can be used in multiple ways. You can send them to your customers via postal mail or hand them out at your store with purchases.

Referral postcards work best when they prominently display the discounts so customers can instantly spot the value in the referral program. Be sure to create an eye-catching, recognizable design with an attractive offer. 

Referral newsletters 

Example of businesses can use newsletters as referral cards

Most businesses have an email newsletter program to share company updates, promotions, new products, and engage with your customers. 

You can leverage them to promote your referral program, too. Instead of generic mass blasts, use marketing agents to optimize your referral outreach. Birdeye’s agents act as a governed extension of your team, continuously A/B testing subject lines, timing, and incentives to ensure your referral newsletters drive the highest possible conversion for every rooftop in your portfolio.  

With referral cards in newsletters, you can also generate new business from otherwise dormant customers by offering them discounts with referrals. The prospect of a discount can motivate them to buy from you again. 

Referral newsletters must be: 

  • Succinct and on topic. Don’t crowd them with other content, links, or product offers. 
  • Use a clearly marked call to action button where people can click to join. Include the link in the body of your text once or twice so users who don’t read to the end can sign up right away.
  • Have easy to download referral cards that people can send to their friends and family.

Referral coupons 

Example of referral coupons

The goal of a good, old-fashioned coupon is to incentivize a purchase with a discount. And that works in referrals too.  

With these, customers receive additional discounts in the form of cash bonuses, a free gift card, and so on. Referral coupons are easy to implement in your business as you can ask your customers to bring them with their person. You don’t need additional technology to use coupons but they are prone to fraud. 

Employee referral card

Example of employee referral forms as referral cards

Incentivize your employees with employee referral cards and programs to tap into employee brand loyalty and grow your business. By offering a bonus to your employees for referring their friends and family, you can leverage your vast employee base and turn them into brand ambassadors. 

Employees feel valuable to the company and the business grows, it’s a win-win all around. Also, employee referrals are often more trustworthy, as people feel they know the company well enough to recommend them.

Referral QR codes

Example of referral QR codes

QR codes bridge the gap between physical interactions and your digital marketing flywheel. When a customer scans a code at a local storefront, Birdeye’s full-cycle agentic marketing platform instantly captures that lead and feeds it into your local intelligence layer, ensuring your brand stays top-of-mind through automated follow-ups and personalized engagement. 

QR codes for referrals can be implemented in a variety of creative ways. 

For example, you can have your customer send their referral QR code to a friend. Or you can use a QR code on business cards, postcards, or emails to direct your customers to specific websites. They can then purchase at a discount or fill out an online referral form.

By customizing the QR code for each customer with an online tool, you can also track where the referral came from.

Online referral forms 

Example of how to use referral forms as referral cards

Online referral forms are usually used in tandem with other types of referral cards mentioned here. You can directly send customers to your referral forms from anywhere, including from your business cards, postcards, flyers, QR codes, and newsletters.

Starbucks uses one for its Rewards Program, where regular customers can sign up to earn free food and coffee. The idea is to send your customers to a specific landing page where they can complete an opt-in form to get credit for the people they’re referring to your business. Those credits can then be applied toward their own purchases, resulting in discounts and free coffee.

Referral flyers 

Example of referral flyers

Flyers or posters serve the same function as referral business cards and postcards. They are displayed in public places and give people other than your customers the opportunity to join your referral program.

This Acorns example demonstrates how companies can use referral flyers to promote their business. 

With this referral card type, you can prompt your audience to go to a web address to learn more about your program or fill out an online form with a well-designed brochure, high-profile poster, or brilliant handouts.  

You can hand out flyers, display them inside your store or at a particular high footfall public space to generate interest in your program.
