Payment cash and digitization in the store

The till is the place where the customer's decision becomes a sale — and where the shop's earnings are finally counted up. Today it is far from just cash that changes hands at the till. As a retail employee, you must be able to handle multiple payment methods, understand the technology that supports them, and know what applies when the shop uses customer data.

§Payment methods today

Most Danish shops today accept debit cards and other payment cards, mobile payment via solutions like MobilePay and, to a decreasing extent, cash. The cash share has decreased in recent years but many shops are still required to be able to accept cash unless they have actively opted out and informed customers clearly. As an employee you must be able to handle all the payment methods your shop offers — and know what you do if a payment fails or is declined.

• 01Payment card (Dankort and international cards) — the vast majority of transactions today
• 02Mobile payment (e.g. MobilePay) — fast and widespread, especially for smaller amounts
• 03Cash — still relevant, but a declining share of sales
• 04Gift cards and store credits — require their own redemption procedures

§Self-checkout tills and digital price tags

Many stores — especially in grocery retail — have introduced self-checkout machines where the customer themselves scans and pays for their goods. It changes your role from standing at the till to helping multiple customers at once: solving errors, helping with age limits (e.g. when buying alcohol) and keeping an eye on the systems functioning. Digital price tags make it possible to update prices and campaigns centrally and immediately, instead of someone having to manually change paper tags in every store.

§Customer data, loyalty card and GDPR

When a customer signs up for a loyalty program or uses a rewards card, the store collects personal information—name, contact details, and often data on what the customer buys. This collection is regulated by the Data Protection Regulation (GDPR), which applies to all companies processing personal information in the EU. This means, among other things, that the store may only use the information for the purpose the customer has been informed about and consented to, data must be stored securely, and the customer has the right to see and in some cases delete their information. The Data Protection Authority oversees that the rules are followed.

• 01The customer must give consent to participate in a loyalty program
• 02Data may only be used for what the customer has been informed about (e.g. offers and points)
• 03The customer has the right to access and deletion of own information
• 04Data must be stored and handled securely in the shop's systems

§What does it mean for you as an employee?

You rarely set up the systems behind data protection yourself, but you often handle customer data in practice: when you create a customer in a loyalty program, look up a customer, or answer a question about how the store uses information. The basic rule is simple — only use customer data for what the customer has been told about, don't share it unnecessarily, and refer a customer to a manager or data protection officer if questions come up about deletion or access that you can't answer yourself.

§The digitalization continues

Click-and-collect, digital receipts, app-based offers and cash registers connected directly to inventory and purchasing are all examples of how technology binds shop and underlying systems more closely together. The better you understand the principles behind payment, cash technology and customer data, the more valuable you become — both in the physical shop and in the digital commerce specialty.
