WS-RFID Technology makes prepaid smart cards for businesses that have been shown to work. Our cards work at 13.56MHz and handle the ISO/IEC 14443 standard. Transactions can be completed in less than 300ms. Each card is made of high-quality PVC material and is 0.76 to 0.84 mm thick. It can last for 10 years or more and has been written on and erased over 100,000 times. We can make more than 500 million units a year and send normal orders within 7 to 12 days, so we can easily support both small pilot projects and city-wide deployments.
During busy times, you need cards that work perfectly. Our prepaid smart card technology makes sure that people can quickly move through gates, which helps avoid lines during busy times.
Fast Transaction Processing
They are not going to wait. It takes less than 300ms for each transaction to finish. This speed keeps the lines going easily, even when tens of thousands of people are using them at the same time.
Built to Last
For more than ten years, these cards have been used every day. The long-lasting PVC material can handle twisting, water, and temperature changes from -25°C to +70°C. The cards always work, no matter if your city has hard weather or tropical heat.
Financial-Grade Security
Every exchange is safe because data is sent encrypted. Features that stop copying and imitation stop theft. Your money stays safe, and people trust the system.

Urban Public Transit
The cars you have work better. People tap and board right away, so there are no problems with cash dealing and drivers have less work to do.
Metro and Light Rail Systems
Processing for entry and leave goes smoothly. Transfer savings are calculated immediately by the system, which encourages people to use more than one mode of transportation.
Parking Facilities
When cars join or leave parking places, they don't stop. It is faster for people to come and go from your places when you accept payments instantly.
Integrated Transportation Hubs
With the same card, you can ride cars, trains, boats, and share bikes. This makes it easy to keep track of cash and brings in more people.
Special Events and Tourism
Put cards out at events, gatherings, or tourist spots. The system is flexible, so it can easily handle temporary high-volume situations.

Your transport system has its own standards for identifying. We allow full customisation, from city logos to unique patterns that build your business. Because you only have to buy 1,000 units at a time, pilot projects are affordable.
You can choose from different chips, like the NXP Mifare line, Desfire, and chips that are made in different countries. Our researchers can help you figure out which new tech will work best with the old ones.
