Dual-slot card reader for phones and laptops

The Radidi K047 is a USB-A and USB-C RFID card reader that accepts both full-size SD and microSD cards up to 2 TB. It works with iPhone 16 and 17 models, MacBook Pro and Air, iPad Pro, Android phones including Samsung S25 and S26, and standard laptops and PCs.

Replaces single-slot or single-port adapters

If you currently carry separate dongles for USB-A and USB-C or a reader that only handles one card format, this unit consolidates both interfaces and both slot types. The upgrade is worth it when you move between devices with different ports and need to read SD and microSD media without swapping cables.

Plug in and read one card at a time

No driver or app installation is required on supported phones and computers; the reader mounts the inserted card immediately. Only one slot can be active at a time, so remove the first card before inserting the second. The compact 0.018 kg body adds negligible bulk to a bag or pocket.

Questions about this item

What are the exact dimensions of the K047 reader so I can check if it fits in my laptop bag pocket?

The reader measures 1.0922 cm long, 7.2898 cm wide and 11.4046 cm high, weighing 0.018 kg.

How do I install the reader on an iPhone 16 or 17, and what is the common mistake?

Plug the USB-C connector directly into the iPhone 16 or 17 port; the mistake is inserting both an SD and a microSD card at once because the reader reads only one card at a time.

When will I need to replace the SD or microSD cards used with this reader?

Replace the memory cards when they reach their 2 TB capacity limit or show read/write errors; the reader itself has no moving parts that wear out.
