Spain's independent retail sector is squeezed from two sides: e-commerce on one end and big retailers like Mercadona, Carrefour, and El Corte Inglés on the other. Both have years of investment in loyalty programs that lock in customers. Independent boutiques, librerías, papelerías, ferreterías, tiendas de regalo, and barrio shops have not had the same option — until 2026.
A digital loyalty program is one of the cheapest tools an independent Spanish retailer can use to compete. According to Bain & Company, a 5% increase in customer retention can boost profits by 25% to 95%. For a retail margin already squeezed by chain pricing, that retention bump can be the difference between a year in the black or red.
This article compares the loyalty apps that work for Spanish retailers in 2026: Fedele, Stocard, Stamp Me, and Square Loyalty.
What to look for in a loyalty app for retail in Spain
- Points-per-euro-spent system: a EUR 5 purchase and a EUR 80 purchase should not earn the same reward
- No extra hardware: the till already has enough on it
- Spanish-language interface: for staff and customers
- Free plan or low entry cost: independent retailers run on tight margins
- Custom rewards: discount voucher, free product, prepaid pack — flexibility matters
- GDPR compliance: required in Spain and the EU
- Apple Wallet support: useful for the iPhone-using share of your customers

Detailed reviews
1. Fedele
Best for: Spanish retailers that want a smartphone-only points program with a free starting plan.
What it does: Fedele is a dedicated loyalty platform for small businesses. The shopkeeper scans the customer's barcode from the store's iPhone or Android, enters the bill amount, and points apply automatically. No tablet, no separate till.
Key features:
- Points per euro spent with custom ratios
- Barcode scanning under 10 seconds
- Unlimited custom rewards (discount voucher, free product, prepaid pack)
- Map visibility — customers in the area find your shop via the app
- Welcome bonus for new members
- No hardware
- Apple Wallet support on the customer app
Pricing: Free plan at EUR 0/month for up to 5 customers. Pro at EUR 49.99/month (annual EUR 599.99) or EUR 59.99/month monthly billing.
Strengths:
- Genuinely free to start, no credit card needed
- Spanish and English interface
- GDPR compliant
- Points-per-euro fits varying purchase sizes (EUR 5 keychain vs. EUR 80 jacket)
- Apple Wallet on iPhone
Limitations:
- Free plan capped at 5 customers (designed as a real test)
- No POS integration (works standalone — by design)
2. Stocard (now part of Klarna)
Best for: Customers who want all loyalty cards in one digital wallet.
What it does: Stocard is a consumer wallet. Customers scan their existing cards and store them on their phone. It does not let retailers create a loyalty program.
Pricing: Free for consumers. No merchant product.
Strengths:
- Polished consumer wallet
- Spanish interface
- Free
- Apple Wallet integration
Limitations:
- You cannot create a loyalty program for your shop with Stocard
- No merchant tools, analytics, or rewards engine
- After the Klarna acquisition, focus shifted to payments and shopping
3. Stamp Me
Best for: Retailers that prefer a stamp card — every visit earns a stamp toward a fixed reward.
What it does: Stamp Me digitizes the stamp card. Customers earn one stamp per visit via QR code, with a reward at a fixed count.
Pricing: From ~EUR 22/month (Lite plan). Free trial available.
Strengths:
- Stamp metaphor is familiar
- 4.9-star App Store rating cited
- Apple Wallet support
- Push notifications and Birthday Club on higher plans
Limitations:
- Stamp model is unfair when purchase sizes vary widely (a EUR 3 magazine and a EUR 200 dress should not earn the same stamp)
- English-first interface and support
- No free plan
- StampPod NFC hardware needed for some validation flows
- Smaller user base in Spain than international markets
4. Square Loyalty
Best for: Retailers already running Square POS for payments.
What it does: Square Loyalty is an add-on to Square POS. Customers earn points automatically at checkout. The pass can sit in Apple Wallet.
Pricing: From $45/month, on top of Square processing fees.
Strengths:
- Frictionless if you already use Square
- Automatic point accrual at the till
- Apple Wallet support
- Spanish interface
Limitations:
- Locked to Square POS
- $45/month on top of existing Square fees
- Cannot be used standalone
- Limited customization vs. dedicated loyalty platforms
Which loyalty app should a Spanish retailer pick?
The deciding factors for most Spanish retailers: speed at the till, fairness across purchase sizes, and cost.
Choose Fedele if:
- You want a free plan to test before committing
- Points per euro spent matters more than stamps
- Spanish interface and GDPR compliance are required
- You do not want to add hardware to the till
- Apple Wallet on iPhone matters to your customers
- You want customers in the neighborhood to discover you via the app's map
Choose Square Loyalty if:
- You already run Square POS
- Automatic points at checkout outweigh customization
- You can absorb $45/month on top of Square fees
Skip Stocard:
- It is a consumer wallet. You cannot create a retail loyalty program with it.
Choose Stamp Me if:
- Your products are uniformly priced (single-SKU shop, fixed-price model)
- You can absorb ~EUR 22+/month
- English-first interface is acceptable
The bottom line
The right loyalty app for a Spanish retailer scales the personal recognition that already keeps regulars coming back. Points should reflect what they actually spend. The interface should speak Spanish. Hardware should not crowd the till.
Fedele was built to fit that brief. Free to start, no hardware, Spanish interface, points per euro. Try it with your next ten regulars.
