Will it keep reading reliably when mounted on metal?
Stock SKU. Custom tooling from 2,000 pcs.
Standard; rush possible on request.
Stock samples via DHL / FedEx.
Use this tag when the asset sits on metal and a standard label or inlay would lose performance. Confirm surface type, mounting method, and required read distance before sample approval.

branded rings issued to attendees for zone access, session tracking, and on-site purchases
Ceramic Ring vs Silicone Ring — How To Choose
Both formats use NFC for tap-to-pay, tap-to-unlock, and smart-home triggers. The physical difference is hardness and scratch tolerance: ceramic for premium look + scratch resistance, silicone for gym / swim / active outdoor use. Pick by the wearer's daily activity profile, not aesthetics alone.
Option A Scratch-resistant zirconia, premium finish
Best for
Option B Flexible, IP68, gym / swim / PPE safe
Best for
Quick decision tip — If the ring is for a premium brand / office / fashion context, ceramic (Option A) at $12-28 delivers the tactile prestige. If the ring is for gym / pool / construction / active-lifestyle daily wear, silicone (Option B) at 1/3 the cost is safer (no shatter, no pinch) and submerge-safe. Many programs offer both tiers on the same NFC backend.
The ring body is manufactured from zirconium oxide (ZrO) ceramic, sintered at over 1400 deg C into a dense, non-porous structure with Mohs hardness 8.5 harder than stainless steel and resistant to everyday scratches that would damage metal or plastic rings. Ceramic is the preferred body material for RFID rings because it is RF-transparent, non-conductive, and chemically inert. Metal ring bodies would shield or detune the embedded HF antenna; ceramic allows the 13.56MHz field to pass through unobstructed, maintaining consistent 1-5 cm read range.
The ring accommodates any 13.56MHz HF chip supported by standard NFC antennas. For access control, MIFARE Classic 1K/4K (S50/S70) and MIFARE DESFire EV1/EV2 variants match most installed door readers. For transit and ticketing, Ultralight C and ICODE SLIX meet fare collection requirements. For NFC smartphone interaction business card sharing, URL launch, app triggers NTAG213/215/216 are the preferred chips with read/write memory from 180 to 924 bytes. The pre-programs rings with customer-specified NDEF records, URLs, or access credentials before shipment.
The ring is available in US sizes 5 through 13, corresponding to inner diameters from 15.7 mm to 22.2 mm. The supplies a printable ring size chart for customer selection, or can pre-sample a size kit for internal fitting. Band width is 7 mm with rounded edges for comfort during extended wear. Weight is approximately 4-6 g depending on size, light enough for all-day wear without fatigue. Chip and antenna are embedded in a sealed cavity fully protected from sweat, water, and everyday mechanical contact.

Buyer Questions
These FAQs cover the points that usually come up between a first shortlist and a real sample or quote request.
For NFC Ceramic Smart Ring, the standard MOQ starts at 200 pieces on stock SKUs. Custom shapes, molds or non-standard materials typically move MOQ to 2,000–5,000 pieces to cover tooling setup. Exact MOQ and unit pricing are quoted per project once chip, customization and packaging are confirmed.
Yes. Stock rfid rings samples of NFC Ceramic Smart Ring are typically free; we only ask buyers to cover DHL/FedEx express shipping. Samples ship in 1–3 business days after your order is confirmed and arrive in 2–5 days to most countries. Custom samples (new chip, new size, printed artwork) usually take 3–7 additional days.
Standard NFC Ceramic Smart Ring orders ship in 7–15 business days after PO confirmation and artwork approval. Large runs (>100k units) or orders with complex encoding / custom molds may take 15–25 business days. Rush production is available on request for time-sensitive launches; confirm MOQ and artwork early to protect the timeline.
Yes. NFC Ceramic Smart Ring supports end-to-end customization: full-color CMYK / silk-screen / UV printing, laser engraving, serial numbering, custom chip encoding (UID write, NDEF, sector locking), custom shape / size (subject to tooling MOQ), and packaging. Share your artwork, chip requirement and quantity and we will return a spec sheet + price within 24 hours.
