This RFID reader module from Shenzhen Chikek Intelligent Tech Co., Ltd. operates at dual frequencies of 125 kHz and 134.2 kHz, supporting a broad range of low-frequency tags. The model CHK103MT features a UART-TTL interface, a power supply range of 3.3V to 5V DC, and consumes less than 45mA. It is designed for integration into embedded systems requiring animal identification or industrial access control.
The module is compatible with ISO 11784/11785 standards, supporting FDX-B animal ear tags, and can read/write Hitag 1, Hitag S 64, Hitag S 256, and Hitag S 2048 tags. It also reads the UID of common EM4100, EM4200, and TK4100 cards. The external antenna, connected via stamp-holes, provides a reading range of 50 to 100 mm, depending on tag and antenna size. The compact PCB measures 25mm x 16.5mm x 2.8mm and weighs 3 grams.
Integrators and OEMs in livestock management, pet identification, and industrial automation source this module for its protocol flexibility and small form factor. The listing provides SDK information including Windows demo software and API documents. When sourcing from Shenzhen, verify the exact antenna specifications, confirm the baud rate configuration (default 9600bps, adjustable up to 115200bps), and discuss MOQ and lead time directly with the supplier.

When sourcing the CHK103MT reader module from Shenzhen Chikek, begin by verifying technical compatibility. Request the full SDK package, including the COM protocol document and API, to confirm it works with your host controller (e.g., Arduino, Raspberry Pi, or custom PCB). Ask for clarification on the external antenna connection specifications and whether they offer pre-matched antennas for optimal 50-100mm range.
Clarify all commercial and logistics terms before placing an order. The listing omits MOQ, unit price, packaging, and lead time. For shipment from Shenzhen, discuss Incoterms (like EXW or FOB), available shipping methods (courier, air, sea), and any required export documentation. Get a formal proforma invoice that includes all agreed specifications and terms.
Establish quality acceptance criteria. Upon receiving samples, test the module's read/write functionality with each tag type you plan to use (Hitag S, EM4100, etc.). Verify the UART communication at your required baud rate and measure the actual current consumption. For bulk orders, agree on a random sampling inspection plan with the supplier to check for consistent performance and build quality before the shipment leaves China.
