NFC self-adhesive labels

Introduction to NFC self-adhesive labels
NFC is a wireless communication technology composed of an antenna and a chip. We call it an inlay. The inlay is placed in a thin layer of paper, then a layer of adhesive is applied to create an NFC sticker label. This label can be attached to objects to carry information. However, it is important not to use it on metal or lithium battery surfaces; pay attention to draining water and avoid external pressure acting on the chip.

NFC self-adhesive label function
It enables fast activation and fast pairing of NFC Bluetooth devices, making it convenient and energy-saving.
NFC is widely used for daily communication and digital content exchange, as well as for connecting and interacting with touchscreen electronic devices. The NFC function allows two phones with this feature to pair quickly with a light tap (pairing time is less than one-tenth of a second, 50 times faster than Bluetooth pairing), enabling data exchange and scene mode switching through such simple and quick touches.

Features and advantages of NFC self-adhesive labels
The most important thing about NFC self-adhesive tags is their low cost. They have a 13.56MHz operating frequency, enabling contactless data and power transmission, with transmission speeds up to 106kbit/s. The 16-bit CRC check code, verification, bit encoding, and bit counting data integrity operation distance can reach up to 100mm, enabling fast command reading and true collision protection. It also has a 50PF input capacitor and an original ECC-based signature.

NFC adhesive label application range
Mobile phone payments, NFC promotional posters, stored-value consumption, points consumption, mutual data connection and data transmission of NFC devices, access control, public transportation, and more. Mobile wallets (mobile payments), micropayments, smart posters, electronic coupons, electronic tickets, vending machines, parking meters, access control and attendance systems, subway systems, membership stored-value consumption management, personnel identification, product identification management.

Common antenna sizes for NFC self-adhesive tags
Standard antennas (76*45), 45*45, 32*32, diameter 22, diameter 25, diameter 33, diameter 40, 12*26, 15.5*52, 22*27, 22*37—these are commonly used sizes for NFC tags, and all sizes are in millimeters (mm).
