Frequently Asked Questions

Cardzgroup offers market-leading pricing combined with the quality oversight of a Western management team. Our directors are former Gemalto UK management with decades of experience in the smart card industry. We maintain rigorous quality control at every stage of production and provide responsive, English-speaking service to clients worldwide. Our Asian manufacturing base delivers significant cost advantages without compromising on quality.

Cardzgroup was founded in 2007 by former members of the Gemalto UK management team who recognised an opportunity to deliver high-quality smart card products at globally competitive prices by leveraging manufacturing in China. The founding team brought with them extensive expertise in card manufacturing, security and quality management from their years at one of the world's largest smart card companies.

Our competitive pricing comes from our manufacturing base in Shenzhen, China, which gives us access to lower production costs, skilled labour and an efficient supply chain. However, we do not compromise on quality: we import premium components from leading chip suppliers such as NXP, Infineon and STMicroelectronics, and every production run is overseen by our experienced management team. The result is first-class products at significantly lower prices than Western manufacturers.

Cardzgroup was founded and is managed by a Western management team. Our senior staff are native English speakers with years of international business experience. All client communication, documentation and technical specifications are handled in English. We operate on familiar business practices and quality standards, so working with Cardzgroup feels no different from working with a company in the UK or Europe.

Quality oversight is embedded into every stage of our manufacturing process. We maintain dedicated production teams in each partner factory who monitor output in real time. Every order is tracked through a stage-by-stage quality control system from incoming raw materials through to final packaging. Our management team conducts regular factory audits and reviews production data to identify and resolve any issues before they affect the finished product.

Yes, and in many cases it exceeds it. We use the same premium chip modules and antenna materials from NXP, Infineon, STMicroelectronics and other tier-one suppliers that are used by the largest European and American card manufacturers. The difference is our manufacturing cost base, not our component quality. Our card bodies, lamination, printing and chip embedding all meet or exceed international ISO standards.

Our QC process includes four key stages: (1) Incoming material inspection, where all raw materials and components are tested against specifications before entering production; (2) In-process quality checks at each manufacturing stage including printing, lamination, chip embedding and encoding; (3) Final quality control inspection of finished cards including visual checks, dimensional measurement and electrical testing; (4) Sample testing from each batch using AQL sampling standards to validate performance against specifications.

Contactless smart cards are plastic cards (typically PVC, PET or polycarbonate) with an embedded RFID or NFC chip and antenna. They communicate with card readers wirelessly using radio frequency technology, typically operating at 13.56 MHz (HF) or 125 kHz (LF). The user simply taps or waves the card near a reader to complete a transaction or gain access. Common applications include public transport fare collection, building access control, hotel key cards, payment cards and identification documents.
