If you want to integrate RFID technology into existing devices to check consumables, find counterfeited spare parts in a machine or identify users, you sometimes do not have the space on your PCB for a complete reader. Often you only have a few square inches of available space to place all the RFID functionality you need. For these cases, the Dwarf14 HF RFID Module is just the right product. It uses MIFARE® Classic and MIFARE Ultralight® protocols.
With a size of only 22 x 39 mm, the module sets a new standard for RFID reader miniaturization. Despite its size, the module has a performance comparable to much bigger RFID readers. With the right antenna, you can even get a read range of 80 mm.
With the use of these production-ready SMD modules, you get tested hardware and firmware in an extremely short time to market. If you need a different form factor or new features there is always the possibility for a customized module.
