WS-RFID Technology's biodegradable hotel key card is both environmentally friendly and works well enough for businesses. Our cards are made from recyclable materials that have been approved by organisations around the world. They also have 125kHz or 13.56MHz chip technology, which lets you read from 5 to 15 cm away and supports over 100,000 write cycles. Our 10,000㎡ automated factory keeps a failure rate below 0.1% even though it can make more than 500 million units a year. Standard shipping only takes 7–10 days, and we offer full OEM/ODM customisation, including printing brand logos and personalised codes. We have more than 15 years of experience making RFID tags.
People who come to your site care about the world. So should your hotel.
It takes a very long time for normal plastic key cards to break down. They hurt environments and add to the trash in dumps. Our item is a better choice instead.
Over time, these cards get worn out on their own. RoHS, REACH, and POPS have all said that they are safe for the earth. You keep the best parts of your hotel while lowering its carbon footprint.
If you use eco-friendly cards, it will also help the image of your brand. Travellers today actively look for places to stay that are good for the environment. They like hotels that take care of the environment. You can reach your ESG goals and get people who care about the world with this choice.
