WB507 · closed-loop textile credential
Elastic RFID Wristbands
Stretch-on fit. Your artwork on the band and patch.
Elastic RFID wristbands use a closed textile loop that stretches over the hand, with no buckle or snap to fasten. The WB507 supplier references list a Ø67 × 25 mm format and a separate Ø55 / Ø65 / Ø70 mm size range. Printed band artwork and a sewn patch provide visible identification; the RFID chip is selected for the venue reader or NFC application.

Product specifications
A textile loop, rather than an adjustable strap.
The wearer slips the band over the hand and removes it the same way. This format suits removable membership credentials and custom event wearables.
For admission that requires evidence of removal, compare a fabric wristband with a one-way fastening.
- Supplier model
- WB507Both original supplier listings identify this model as an elastic closed loop.
- Construction
- Closed textile loop with a sewn patchThe photographs show a printed band and stitching around the patch, with no buckle or snap. The IC and antenna are not exposed in these views.
- Material
- Nylon / fabric in the source listingsExact fiber blend and elastic composition are not specified. Include any material requirement when choosing a production sample.
- Nominal sizes
- Ø67 × 25 mm; Ø55 / Ø65 / Ø70 mmTwo published size sets, retained separately below. Diameter is not a wrist-circumference rating.
- Decoration
- Heat-transfer print, screen print or woven artworkChoose the band artwork and patch treatment separately. The photos show both outward-facing graphics and inner-band printing.
- RFID selection
- LF identification or HF / NFC, depending on the ICPublished LF and HF families are alternatives. A single selected band does not automatically support every frequency or reader.

WB507 appears in two supplier listings with different nominal sizes. The references below preserve those published dimensions; they are not four measured wrist ranges or a claim that every artwork photo has the same size.

Hand passage and wrist fit are two measurements.
A loop needs to pass over the hand without overstressing its seam, then sit comfortably at rest. Supply the wearer’s wrist circumference and check passage over the widest part of the hand using the proposed sample. A listed diameter does not establish stretch force, recovery or an adult/child size rating.
Original product photographs
Plan the band artwork and patch separately.
The reference samples show a continuous printed loop, a stitched front patch and an inner surface that can carry text. Keep essential text and machine-readable codes clear of the seam.
Inner surface and seam
Inner-band text and the reverse of the patch are visible. No dimension scale or stretch force is shown in this photograph.

WB507 catalogue reference
The supplier lists WB507 as an elastic closed-loop band. This catalogue photograph is an artwork example, not a separate adjustable nylon-buckle model.
Open original photograph ↗Printing and woven decoration
The supplier lists heat-transfer printing, screen printing and woven decoration. Show whether your design belongs on the outer band, inner band or patch. For numbers or QR codes, provide the data and positioning separately from the repeating background artwork.
RFID & NFC selection
Choose the data format your reader actually uses.
These IC references explain the LF and HF families named in the supplier listings. They do not identify the hidden chip in a photograph or turn one band into a multi-frequency credential.
| Chip reference | Interface & memory | Use and compatibility |
|---|---|---|
| EM4200Manufacturer datasheet ↗ | LF identification · commonly specified at 125 kHzFactory-programmed read-only identifier | An installed LF access system using the selected encoding and ID format. It cannot hold a rewritable NFC web link. |
| NTAG213 / NTAG215 / NTAG216Manufacturer datasheet ↗ | 13.56 MHz · NFC Forum Type 2 · ISO/IEC 14443 A144 / 504 / 888 bytes user memory | NFC links or NDEF content. Payload formatting takes some memory. A phone-readable link alone does not grant membership or admission. |
| MIFARE Classic EV1 1KManufacturer datasheet ↗ | 13.56 MHz · ISO/IEC 14443 A activation · Classic commands1 kB total EEPROM · 16 sectors | An existing Classic credential system with the required sector layout and keys. The total includes manufacturer data and sector trailers; it is not 1 kB of unrestricted payload. |
Test the assembled band while worn with the intended reader. Read distance, washing performance and stretch life depend on the finished construction; IC memory specifications do not establish those properties.

Sample ordering terms →Elastic wristband questions
What sizes are published for WB507 elastic wristbands?
One supplier listing gives Ø67 mm diameter × 25 mm band width. Another lists Ø55, Ø65 and Ø70 mm without specifying width. These are separate published references, not a tested stretch range. The source tables do not define inner or outer diameter, stretch state or tolerances, so a finished sample is needed to establish the comfortable wrist fit.
Is an elastic RFID wristband suitable for non-transferable admission?
The closed loop is designed to stretch on and off. It has no one-way lock or break-on-removal fastener, so the band alone does not prevent a wearer passing it to someone else. For admission where removal should leave evidence, compare a fabric band with a one-way lock or a disposable snap wristband, together with the ticketing system controls.
Can the band and sewn patch use different artwork?
Yes. The reference photos show a patterned band and a separate stitched patch, and one inside view also shows text on the inner surface. The supplier lists heat-transfer printing, screen printing and woven decoration. Use separate artwork areas for the band and patch so the seam does not obscure a logo, number or QR code.
Can I use the same band for a phone link and a gym entrance?
Only if the selected chip and the gym system support that use. NTAG21x provides NFC Type 2 memory for links and NDEF content. EM4200 is a read-only LF identifier, while MIFARE Classic uses a different command set and sector configuration. The venue software must register and authorize the credential; the printed design does not determine reader compatibility.
