Smart card is a generic term for a plastic card embedded with a microchip. Smart cards are classified according to the type of embedded chip: memory card, logic encryption card, CPU card, and also classified by power supply: active card and passive card. Active card- contains a power supply device (battery), and even has a screen, keyboard; Passive cards are powered externally. So smart cards require built-in batteries or outside power supply to meet daily use.
Global Positioning Systems (GPS) can provide accurate location data for all kinds of terrestrial and avian wildlife research and management projects. GPS tracking technology has been adopted in the management of movable assets. Tracking systems are normally powered by an individual battery: a rechargeable Lithium-Polymer battery. The battery type chosen for the product is dependent on the device's application environment.
Industrial WiFi routing device is a kind of data transmission function device that uses public wireless network to provide users with wireless. It has been widely used in M2M industry in IoT industry chain, such as smart home, mobile POS terminal, supply chain automation, industrial automation, public safety, environmental protection, digital medical and other fields. At present, industrial wifi routing devices are supported by built-in lithium battery power supply, supporting 4-way POE port, which can provide stable power supply for external devices. The unique built-in high rate battery design and peripheral power supply function can provide continuous power supply for the device in case of accidental power failure, effectively preventing abnormalities in the collected data caused by power failure.
Handheld walkie-talkies are widely used in petrochemical, hotel, restaurant, and school settings. They are powered by a built-in rechargeable battery. However, in cold areas, conventional batteries cannot supply power normally, necessitating low-temperature batteries. Consequently, low-temperature walkie-talkies become an important selection factor for consumers.
A tracker card typically refers to a thin, card-shaped device equipped with tracking technology that is used to locate and monitor the whereabouts of items, such as wallets, keys, or other personal belongings. These tracker cards are often designed to fit into small spaces, like a wallet or a card slot, without adding much thickness. They usually utilize technologies like Bluetooth or other positioning systems to communicate with a smartphone or other devices.
