Wallet cards
Tracker cards fit wallets, ID sleeves, and card holders, with focus on cold pressing, battery life, antenna, and buzzer.
Industry / Consumer Electronics
Consumer electronics and luggage accessories require the right finding ecosystem, battery life, finish, acoustics, antenna clearance, and consistent production quality.

Tracker cards fit wallets, ID sleeves, and card holders, with focus on cold pressing, battery life, antenna, and buzzer.
For luggage tags, embedded bag products, and gifts, with emphasis on finish, waterproofing, acoustics, and the target finding ecosystem.
For customer enclosures or finished devices, with focus on PCBA size, antenna, button/sound openings, and test points.
Product and Engineering
Wallet cards, luggage labels, tags, and embedded PCBAs have different requirements for thickness, battery, buzzer output, buttons, antenna clearance, and protection. Products for iPhone, Android, or Samsung users also require different pairing, naming, platform onboarding, and testing. Yuli can supply FindMy hardware, cold-press manufacturing, or both as a finished card product.
Fits wallets and card holders, balancing thickness and battery life around the battery, buzzer, antenna, and card body.
Fits an existing enclosure or device; confirm board outline, antenna, test points, button, and sound-port interfaces.
The five-year-plus design target depends on the chipset, firmware, battery, advertising interval, buzzer use, and operating environment, and is verified on the finished product.
