Frequently Asked Questions
Everything you need to know about RFID cards for EV charging networks. Can't find your answer? Contact us.
Ordering & Pricing
What is the minimum order quantity (MOQ)?
Our standard MOQ is 500 cards for recycled PVC and bio cards. Wooden cards have a lower MOQ of 250 pieces. For custom OEM/ODM solutions, MOQ varies depending on specifications. Contact us for a tailored quote.
How do I get a quote for EV charging RFID cards?
Submit a quote request through our contact form with your requirements: card type, quantity, chip preference, branding needs, and any network integration details. We respond within 24 hours with a detailed proposal including pricing tiers.
Do you offer volume discounts?
Yes. Pricing scales with quantity — larger orders receive better per-unit pricing. We also offer annual supply agreements for charging network operators with recurring card needs, providing predictable budgeting and priority production scheduling.
What payment methods do you accept?
We accept bank wire transfer (T/T), PayPal, and letters of credit for large orders. Standard terms are 30% deposit with balance before shipment. For established partners, we offer NET 30 payment terms.
Product & Technology
What RFID frequencies do your EV charging cards support?
Our EV charging cards primarily use High Frequency (13.56MHz) technology, which is the standard for charging station authentication. We support MIFARE Classic 1K/4K, MIFARE DESFire EV2/EV3, and NFC (NTAG) chips. Low Frequency (125kHz) options like EM4100 are available for legacy systems. Dual-frequency cards can also be manufactured.
Are your cards compatible with OCPP-based charging stations?
Yes. Our RFID cards work with all OCPP 1.6 and OCPP 2.0.1 compliant charging stations. The cards authenticate via standard RFID readers and are compatible with roaming platforms including Hubject, Gireve, and e-clearing.net for cross-network interoperability.
What chip options are available for charging cards?
We support MIFARE Classic 1K/4K (cost-effective fleet cards), MIFARE DESFire EV2/EV3 (high-security with AES-128 encryption), NTAG 213/215/216 (NFC-enabled), and custom chip configurations. DESFire EV3 is recommended for networks requiring anti-cloning protection and mutual authentication.
How durable are your RFID charging cards?
Our cards are built for daily use in demanding environments. PVC and bio cards are rated for 3-5 years of regular tapping, withstanding moisture, UV exposure, temperature extremes (-25C to 60C), and repeated bending. Each card is tested to over 100,000 read cycles. Wooden cards offer similar longevity with a protective coating.
How do your cards compare to ISO 15118 Plug and Charge?
RFID cards and Plug and Charge serve complementary roles. ISO 15118 authenticates the vehicle, while RFID cards authenticate the driver — essential for fleet management where multiple drivers share vehicles. Most modern charging networks implement both authentication methods. Our cards work alongside Plug and Charge infrastructure.
Sustainability
What recycled materials do you use?
Our recycled PVC cards use 100% post-consumer recycled PVC. The recycled material undergoes rigorous processing to meet the same durability and print quality standards as virgin PVC. The result is a card that performs identically while reducing virgin plastic consumption and diverting waste from landfills.
Are your wooden cards FSC certified?
Yes. Our wooden RFID cards are manufactured from FSC-certified cherry wood or bamboo, ensuring the wood comes from responsibly managed forests. Each batch includes FSC chain-of-custody documentation for your sustainability reporting.
Are the bio cards truly biodegradable?
Yes. Our PPH (Polypropylene Homopolymer) bio cards are designed to naturally decompose at end of life under composting conditions. During their service life, they remain durable, moisture-resistant, and fully functional. This eliminates the long-term plastic waste associated with traditional PVC cards.
How do your products reduce carbon footprint?
Recycled PVC cards reduce carbon emissions by up to 75% compared to virgin PVC production. Wooden cards are carbon-negative as the wood stores carbon. Our manufacturing facility uses renewable energy and holds ISO 14001 environmental management certification. We provide carbon footprint data per order for your ESG reporting.
Customization
Can you print our charging network branding?
Yes. We offer full-color offset and digital printing on both sides of PVC and bio cards. Options include network logos, custom color schemes, QR codes, serial numbers, and variable data printing. Wooden cards support laser engraving and single-color print for branding.
Can you pre-program RFID chips with our network credentials?
Yes. We offer chip programming and encoding services including UID assignment, sector key configuration, application data writing, and NDEF formatting for NFC cards. We can program cards to your charging network's specifications for plug-and-play deployment.
What custom form factors are available beyond standard cards?
Beyond standard CR80 cards, we manufacture RFID key fobs, wristbands, windshield tags (for fleet vehicles), and custom shapes. All form factors support the same RFID chip options and can be branded to your network identity.
Can you integrate our cards with Hubject or other roaming platforms?
Yes. We work with charging network operators to ensure card credentials are properly configured for roaming platforms including Hubject (intercharge), Gireve, and e-clearing.net. Our team provides integration consulting to streamline the setup process.
Shipping & Lead Times
What are your standard lead times?
Standard recycled PVC and bio cards: 2-3 weeks from order confirmation. Wooden cards: 3-4 weeks. Custom OEM/ODM solutions: 4-8 weeks depending on complexity. Express production is available for urgent orders at additional cost.
Do you ship internationally?
Yes. We ship worldwide via DHL, FedEx, and UPS with full tracking. Shipping costs are calculated based on order weight and destination. We handle all export documentation and customs declarations. Most European and North American deliveries arrive within 5-7 business days.
Can I get samples before placing a bulk order?
Yes. We provide sample kits for qualified charging network operators and fleet managers. Sample kits include cards with different materials (recycled PVC, wood, bio) and chip types so you can test compatibility with your charging stations and backend systems.
