The EU AI Regulation (Regulation (EU) 2024/1689, effective from 1 August 2024) classifies AI systems into four risk classes and requires manufacturers and operators of intelligent vending machines to demonstrate tiered compliance, which becomes fully effective between February 2025 and August 2027. For the vending industry, the most relevant areas are age verification systems via camera analysis, biometric access control, and AI-driven personalisation.

The Allensbach 2025 Study on payment behaviour is a representative survey by the Institute for Demoscopy Allensbach that for the first time demonstrates that a majority of Germans prefer card or digital payment methods over cash. It marks the turning point in German payment behaviour and serves as a reference document for investment decisions on cashless systems in the vending and retail sectors.

Related:MDB

BDV

Industry

BDV (Bundesverband Automatenwirtschaft e.V.): National trade association of the German vending industry. Represents operators, manufacturers and suppliers to government and the public; publishes annual market data for the German vending market.

BFSG

Compliance

Accessibility Strengthening Act — as of June 2025, self-service terminals and vending machines with cashless payment must be accessible (reach height, contrast, audio feedback).

BFSG compliance means meeting all requirements of the Barrierefreiheitsstärkungsgesetz (BFSG), which has been mandatory for self-service terminals and payment systems in Germany since 28 June 2025. The law implements EU Directive 2019/882/EU (European Accessibility Act) into German law and obligates manufacturers and operators to make their products and interfaces accessible to people with disabilities.

Brew pressure

Hot Beverage Technology

Water pressure as it flows through the coffee puck in the brew group; 9 bar is the espresso standard. Excessive pressure (>10 bar) produces bitter over-extraction; insufficient pressure (<7 bar) produces weak, acidic under-extraction. In vending machines, brew pressure is fixed; on commercial-grade machines, it is adjustable.

C

9 terms

Carbonation

Water Dispensers

Introducing CO₂ into water under pressure to produce carbonated water. In POU dispensers, this is achieved using replaceable CO₂ cartridges (600 g ≈ 60 L sparkling water) or stainless steel bottles (2–10 kg). Consumption depends on carbonation intensity and water flow rate.

Coffee Puck

Hot Beverage Technology

A compressed disc of spent coffee grounds ejected from the brew group after brewing. A proper puck (uniform, 6–7 g residual moisture) indicates optimal extraction; overly wet or crumbly appearance suggests grinding or dosing problems.

CSRD

Sustainability

Corporate Sustainability Reporting Directive: EU Directive (2022/2464) requiring companies with >250 employees or >€40 million revenue to report on sustainability performance (ESG) according to ESRS standards from 2026. Vending operators supply data on energy consumption, refrigerant and packaging waste.

D

3 terms

Deposit Scheme

Compliance

Legal framework governing single-use and multi-use deposit requirements in Germany. Since 2022, single-use deposit has applied comprehensively to plastic beverage packaging and cans.

DEX

Software

Data Exchange — serial interface (RS-232) through which vending machines transmit inventory and sales data to collection devices or telemetry modules.

Dynamic Pricing

Payment Technology

Automatic price adjustment at the vending machine based on time of day, demand or remaining stock. Example: fresh products become cheaper shortly before expiration; hot beverages cost more in the morning than the afternoon. Technically feasible via remote price control in the VMS; in Germany raises no food-law concerns, though competition-law review is advisable.

E

7 terms

Eco-Mode

Sustainability

Energy-saving operation mode for vending machines: Reduces heating output, lighting and display brightness during non-peak hours. Savings vary by machine type and operating schedule—typically 200–500 kWh/year, equating to approximately 55–140 EUR and 60–150 kg CO₂ per machine per year at 0.28 EUR/kWh.

The Ecodesign Energy Efficiency Class under Regulation (EU) 2019/2024 classifies refrigerated direct-sales appliances (cooled vending machines) using a calculated Energy Efficiency Index (EEI) that relates the appliance's standardised annual energy consumption to a category-specific reference value. Since March 2023, new units may only be placed on the market if their EEI does not exceed the statutory maximum of 55.

This article was created with AI assistance and checked automatically. A human review before publication is not documented. EU ecodesign and energy-labelling rules can apply to refrigerated vending machines when they fall within the category of refrigerating appliances with a direct sales function. The exact classification depends on the machine design and its product documentation.

EPS v2 (Electronic Payment Specification Version 2) is an open interface standard of the European Vending & Coffee Service Association (EVA) that defines communication between machine control systems and cashless payment terminals for contactless EMV transactions. Certified terminals to this standard are vendor-neutral and interchangeable without requiring machine control modifications.

Related:MDBNFC

EVA

Industry

European Vending & Coffee Service Association: European trade association for the vending industry, based in Brussels. Publishes market statistics, standards (EVA-DTS, NAMA Energy Certificate), and advocates for the industry. National representation in Germany: BDV (Bundesverband Automatenwirtschaft).

EVA-DTS

Software

European Vending Association Data Transfer Standard — defines how sales and audit data are read from the vending machine. Current version: 6.2.

Executive protocol

Payment Technology

Older serial communication protocol for vending machines (Riveria/Crane standard), predecessor to MDB. Still found in legacy equipment; cashless terminals for Executive are now rare — migrate to MDB when retrofitting.

F

6 terms

FEFO means first expired, first out: products with the earliest relevant date are sold first or placed at the front. In vending machines, this reduces the risk of earlier-dated batches being left behind while stock with a later date remains available.

Refrigerated vending machine for fresh food items: sandwiches, salads, fruit, prepared meals. Operated with compressor refrigeration (4–8 °C) or combination refrigeration. Most hygienically demanding vending machine category; HACCP documentation and daily restocking are mandatory.

Full-service contract

Operator Ecosystem

Full-service maintenance contract where the operator provides and maintains the machine, supplies and restocks products, and handles all maintenance, repairs and spare parts. Billed either as a monthly flat fee or revenue share. Eliminates capital expenditure and in-house operational labor; location owners receive lower margins compared to in-house operation.

G

2 terms

GWP

Sustainability

Global Warming Potential: a measure quantifying the warming potential of a substance relative to CO₂ (GWP = 1). R290 (propane) has GWP 3; obsolete F-gases such as R404A have GWP 3.920. The F-Gas Regulation limits the use of refrigerants with GWP >150, making R290 the standard in new refrigerated vending machines.

H

2 terms

HACCP

Compliance

Hazard Analysis and Critical Control Points — hygiene system for food-handling vending machines. Mandatory for, among others, fresh milk, fresh food and hot beverage systems.

This article was created with AI assistance and checked automatically. No human review before publication is documented. HACCP is a preventive self-monitoring system that food businesses use to identify, monitor and control biological, chemical and physical hazards through documented measures. For vending operators, it translates hygiene requirements into practical procedures for goods receiving, refrigeration, cleaning, maintenance and incidents.

L

3 terms

Legal Metrology

Compliance

Legal framework (MessEG, MessEV) governing the accuracy of measuring equipment in commercial transactions. Relevant for vending machines: weight- or volume-based pricing (e.g. coffee in grams, water flow in litres) requires calibrated measurement units. Calibration compliance is verified by the calibration authority (state office).

LMIV

Compliance

Food Information Regulation (EU 1169/2011): mandates labelling of ingredients, allergens, nutritional values and origin. At vending machines, the 14 main allergens listed in Annex II must be visibly marked either directly on the packaging or via posted notice or on-screen display.

Locker Machine

Machine Types

Locker machine for secure, controlled dispensing of goods (medicines, tools, mobile devices, food). Each compartment is individually electronically secured; access via PIN, QR code or NFC card. Deployed in pharmacies, hospitals and industrial facilities.

M

NFC

Payment Technology

Near Field Communication — contactless radio connection over a few centimetres. Foundation for Tap-to-Pay with card, smartphone or employee badge at the vending machine.

O

3 terms

Open-Loop Payment

Payment Technology

Open payment system universally accepted — girocard, credit card, NFC, Apple Pay. Opposite of Closed-Loop. Standard in modern vending; enables purchase without prior registration. Requires bank integration and transaction fees (approx. 0.3–1.5% per transaction).

Period during which a machine is unavailable due to malfunction, maintenance, or empty stock. Direct impact on revenue and customer satisfaction. Industry benchmark: out-of-service time below 2% of operating time is considered excellent.

P

5 terms

Packaging tax is a municipal levy on single-use containers for food and beverages for takeaway that individual German cities have independently collected since 2022. The operator who first places the single-use container in circulation is liable for tax; reusable containers are explicitly exempt in all ordinances enacted to date.

Predictive maintenance: telemetry and sensor data are analyzed to forecast failures and schedule maintenance based on need — rather than at fixed intervals. In practice in 2026, this typically involves rule-based anomaly detection (vibration, temperature drift); true ML-based forecasting is only viable for large fleets (100+ units).

Prepaid Account

Payment Technology

Prepayment model for vending-machine payment systems: users load a digital balance (via app or loading station) and pay for purchases without real-time bank connection. Reduces transaction costs and enables employer contribution models (e.g. 50% employer contribution).

R

7 terms

R290

Sustainability

Propane refrigerant with very low global warming potential (GWP 3). Increasingly becoming the standard in cooling vending machines and smart fridges, replacing climate-damaging F-gases.

Feature of vending management systems to change product prices remotely without physical technician visits. Enables real-time price adjustment based on raw material costs, time of day (Dynamic Pricing), or location groups.

Retrograde contamination refers to the migration of microorganisms from the dispense point (nozzle or tap) against the flow direction into the interior of a water dispenser or drinking water installation. Triggers are capillary forces, negative pressure effects and residual droplets after the dispense cycle, through which microorganisms from ambient air or contaminated surfaces enter the pipe run or storage tank.

Reusable Cup System

Sustainability

Reusable cup system for hot beverage vending machines: users bring their own cup or use a deposit system (e.g. RECUP). Reduces packaging waste per 100 servings from approximately 0.8 kg to nearly zero. Since 2025, economically more attractive due to regulatory fees on single-use plastics.

Reverse osmosis

Water Dispensers

Water filtration technique that, through pressurization (4–10 bar), removes nearly all dissolved salts, heavy metals and pathogens from tap water. Result: very pure, tasteless water (TDS <10 ppm). For POU sparkling water dispensers, frequently combined with a remineralization stage, because pure water tastes bland.

Route

Operations

Planned sequence of visits by a service technician to multiple vending machine locations. Optimized routes reduce travel costs and ensure machines do not run out of stock. VMS systems calculate routes dynamically based on reported fill-level data.

S

10 terms

Scope 3 Emissions

Sustainability

Indirect greenhouse gas emissions across a company's value chain (upstream and downstream) — in contrast to direct Scope 1 and energy-related Scope 2 emissions. Vending machines and their stocking logistics typically fall under Scope 3, Category 1 (purchased goods/services) for location owners. Under CSRD, Scope 3 must be fully accounted for.

A secret pack machine dispenses sealed surprise packages whose specific contents are not fully known at the point of purchase. The term describes a sales format primarily, rather than automatically establishing a particular legal classification. Categorisation depends on factors including contents, price, winning expectations, winning possibility, randomisation mechanism and the specific structure of the offering.

Share of stocked products that are actually sold within a defined period (usually per stocking cycle). High sell-through rate = well-matched assortment; low rate indicates wrong product selection or overstocking.

The designated time interval between regular maintenance visits by a technician. Typical: 30/90/365-day cycles. Intervals that are too short increase service costs; intervals that are too long increase the risk of machine failures. Modern IoT platforms replace fixed intervals with condition-based maintenance (Predictive Maintenance) as telemetry data becomes available.

Sielaff

Industry

German manufacturer of reverse vending machines (RVM) and vending machines based in Georgensgmünd, Bavaria. Market position: challenger to Tomra in the German-speaking mid-market segment; known for value for money and short regional service routes.

Site Commission

Operator Ecosystem

Revenue share that an operator pays to a venue owner for placement space. Typical: 10–15 % of net revenue; in high-traffic prime locations up to 25 %. Alternative: fixed site fee (20–150 EUR/month). The amount is negotiable and depends on foot traffic, exclusivity, and contract duration.

Smart Fridge

Machine Types

Refrigerated cabinet equipped with sensors or cameras that automatically detects removed items and settles payment after the door closes (Grab-and-Go, no keypad required).

The Supply Chain Due Diligence Act (LkSG) obliges companies with 1,000 or more employees (as of January 1, 2024) to systematically identify, assess and document human rights and environmental risks across their entire supply chains. For vending operators, this primarily affects procurement chains for coffee, cocoa, tea and fruit juices from high-risk regions.

T

6 terms

Throughput

Operations

Number of vends from a machine per time unit — hour, day or month. Essential for machine category selection (hot beverages: 80–150 cups/hour for office machines, 200+ for high-performance machines) and for cost-effectiveness analysis. Excessive throughput for an undersized machine causes continuous duty and premature wear.

TrinkwV

Compliance

Drinking Water Ordinance (TrinkwV 2001, amended 2023): establishes limit values for microorganisms, contaminants and chemical parameters in drinking water. Operators of POU water dispensers must ensure water dispensed at the outlet meets these limit values — filter replacement and hygiene checks are mandatory record-keeping requirements.

V

3 terms

TCO means total cost of ownership: the costs of acquiring, operating, maintaining and disposing of a vending machine. For operators, it is more informative than purchase price alone because it makes ongoing and later costs visible.

VerpackG

Compliance

Packaging Act (valid since 2019, amended multiple times): Manufacturers and marketers of packaging must register with the Central Packaging Register (LUCID) and pay licensing fees. Also applies to vending operators who sell packaged goods.

VMS

Software

Vending Management System: software platform for centralized management of multiple machines. Functions: telemetry monitoring, sales statistics, route planning, remote pricing control, and malfunction alerting. Market-leading platforms: Nayax, Cantaloupe, Invenda.

W

Water Hardness

Water Dispensers

Calcium and magnesium content of tap water, measured in degrees German hardness (°dH). Classification: soft <8.4 °dH, medium 8.4–14 °dH, hard >14 °dH. High °dH accelerates limescale deposits in coffee machines and POU dispensers — requires shorter descaling intervals or a water softening system. Published by water suppliers for each supply area.
