Import 4sam/Cpu Card Reader/Writer, Dual Rfid — Buy in wholesale FOB from Supplier in China

The 4SAM/CPU Card Reader/Writer, Dual RFID from Shenzhen Chikek Intelligent Tech Co., Ltd. is a compact device designed for contactless and PSAM card operations, supporting ISO14443 A/B, ISO15693, and ISO7816 T=0 standards. It operates on a 3.3V to 5V DC power supply with a current draw under 150mA, featuring UART TTL or RS232 interfaces for seamless integration. The unit includes four internal PSAM sockets and an external antenna connector (1.25 2P or IPX), achieving a reading range of 50 to 70mm depending on tag and antenna specifications.

Constructed from FR-4 material with a blue finish, the model CHK362MT measures 76mm x 50mm x 2.8mm and weighs just 10g, making it suitable for embedded applications where space is constrained. It supports a broad range of tags, including MIFARE Classic 1K/4K, Ultralight, DESFire, and ISO14443A-4 contactless CPU cards, alongside ISO15693-compliant tags like I-Code SLI and EM4x33 series. The device is factory-calibrated to 13.56MHz with a baud rate configurable from 9600 to 115200 bps, defaulting to 115200 for high-speed data transfer.

This reader is deployed in access control systems, payment terminals, and identity verification setups where dual-interface card compatibility is critical. Buyers typically source it for OEM integration into kiosks, POS systems, or industrial automation rigs. The unit’s environmental tolerance spans -20°C to +80°C for operation and -40°C to +85°C for storage, with relative humidity resistance from 5% to 95%. Confirm compatibility with your host system’s voltage and communication protocol before ordering, as the device does not include a power adapter or host interface cables.
