Miele PCI DSS case study

Miele is  a leading premium domestic and commercial appliances manufacturer. This case study explains how it is using Syntec’s CardEasy secure keypad payment by phone system in order to descope its call center and call recordings from PCI DSS requirements.

Cloud/hosted CardEasy service

  • Miele was originally considering a premise-based touchtone payment (DTMF) system to de-scope its call center environment and call recordings from PCI DSS regulations,  with its agents still taking payments from customers in mid-conversation
  • The fully-hosted version of the CardEasy keypad payment by phone solution turned out to be more attractive for Miele, because the sensitive card data never enters the call center environment, thus reducing PCI DSS compliance requirements almost to nil with just a minimal self-assessment questionnaire (SAQ) to complete
  • The hosted CardEasy solution proved quick and easy to trial and subsequently deploy with no new equipment needed (as it integrates with existing phones and payment systems on an SaaS basis)
  • CardEasy was integrated with Miele’s payment gateway for easy trial and rollout (CardEasy is now integrated with nearly all major PSPs on behalf of Syntec’s CardEasy clients)
  • As an Ofcom-regulated telecommunications provider, Syntec was also able to give Miele expert advice on integrating CardEasy into its existing infrastructure, with recommendations such as the option to change phone numbers to generate revenue-share from call charges where appropriate


Miele achieved PCI DSS level 1 with mid-call secure payment; improved transaction speed and customer service; and with no capital expenditure outlay.

Miele is so satisfied with the CardEasy system that it is now integrating this with Syntec’s AgentCall contact center management solutions across its operations.

Miele selected Syntec’s pioneering, hosted CardEasy system to enrich customer service whilst de-scoping us from large sections of PCI DSS regulations, which otherwise require significant cost and effort to satisfy.

  • 95% of transactions went through CardEasy on day 1 of launch, with no age barrier to take up
  • Shorter call times due to one less process (of agent taking card numbers before entering them)
  • Less miskeying results due to this removed process too

Examples of Miele customer feedback

“Oh OK, that’s a good idea – it’s nice to know my card details are kept safe”

“I wish more companies handled my card security this way”

Examples of Agent feedback

“Quick and simple, easy to go through with the customer, faster than taking card numbers and more secure”

“Great for the majority of calls, a few calls require special handling, but this was always the case”
