Case Study: Ralph’s Supermercado Modernises Checkout with HiStone in Puerto Rico

10 Oct 2026

Customer: Ralph’s Supermercado  |  Location: San Juan, Puerto Rico  |  Sector: Grocery  |  Hardware: HiStone HS520U, HS610M, HS710

Ralph’s Supermercado is a local supermarket chain with 13 stores across Puerto Rico. Facing long queues and a customer base that still relies heavily on cash, it worked with HiStone and local partners to modernise checkout, starting at its Montehiedra store in San Juan. This supermarket self-checkout case study shows how card and cash self-service can work side by side.

The challenge

  • Long checkout lines at busy times.
  • Difficulty moving staff between departments.
  • A need to accept both cards and cash, as many shoppers pay in cash.
  • A desire for a more modern, easy-to-use checkout.

President José Soto summed it up: “We knew we needed to streamline checkout to keep up with shopper demand.”

The solution

HiStone installed HS520U self-checkout units at Montehiedra, some paired with a PayPod automated cash module from Crane Payment Innovations and some in standard card-only configuration. HiStone describes it as the first HS520U and PayPod installation in the Americas. The HS520U was chosen for its design, durability in high-traffic environments and flexible payment options, and installation took around two weeks.

Project partners

  • Girboy Technologies: regional distributor.
  • Multi Business Systems: software vendor and systems integrator.
  • Crane Payment Innovations: PayPod cash automation.

The results

  • Shorter queues and smoother customer flow.
  • Self-checkout adopted by shoppers of all ages and payment preferences.
  • Staff freed to spend more time with customers.
  • Cash transactions automated with less manual handling.
  • HiStone self-checkouts now running in all 13 stores, using HS520U, HS610M and HS710 models.
