The main feature of FPC is that it perfectly fits elastic wristbands and is flexible. and waterproof.

Elastic wristbands undergo frequent stretching and bending during use. FPCs use a polyimide (PI) substrate, which can deform slightly along with the wristband without damaging the circuitry.

The PFC tag is resistant to sweat and frequent wear, making it the best choice for long-term membership wristbands.

Assembly Methods:

Built-in Leather Label Encapsulation: The FPC chip is encapsulated within a silicone or microfiber leather label, which is then sewn onto an elastic fabric strap.

Hot-press Process: The encapsulated FPC label is directly fixed to the inside of the wristband using hot-press technology.

"FPC Inside": Emphasizes that your flexible wristband uses an FPC copper foil antenna instead of a cheap PET aluminum antenna. This represents higher read/write stability, water resistance, and a longer lifespan.

Stretch Protection: Explains how your encapsulation process prevents the FPC antenna from breaking when the wristband is stretched violently.

Application Scenarios:

Music Festivals: Combines with NFC FPC for high-speed entry and cashless payments.

Gyms/Hotels: FPC tags are resistant to sweat and frequent wear, making them the best choice for long-term membership wristbands.

When a user's phone is brought close to the wristband (approximately 1-3 cm), the phone's NFC antenna generates an alternating magnetic field. 

The NFC FPC antenna inside the wristband obtains energy through induced current, instantly "activating" the chip.

Once activated, the chip will send a pre-set redirect link (URL) back to the phone via radio waves.

Why choose FPC mateiral in this Elastic wristband ?

FPC reinforcement: It must be ensured that the FPC antenna will not experience metal fatigue fracture when the fabric is stretched to its maximum extent.

Waterproof encapsulation: Since the ribbon wristband is typically worn all day, it must meet an IP67/68 waterproof rating to ensure continued usability after 

handwashing or showering.
