H210-U 13.56MHz USB stick NFC reader, white housing with key ring

H210-U 13.56MHz USB Stick NFC Reader for MIFARE Cards, Plug-In

Q: Does the H210-U work with Android phones?

Yes, through a USB OTG adapter on phones and tablets that support OTG. It types the card number into the app that has focus, like a keyboard. For a direct USB-C plug-in, see the H220-C.

Q: Does the H210-U work with an iPhone?

iOS is not on the H210-U's supported list, so we do not offer it for iPhone or iPad.

Q: How big is the H210-U?

75 × 21 × 7 mm and about 10 g, or about 40 g in its retail box. It has a cap over the USB plug and a key ring.

Q: Which cards does the H210-U read?

MIFARE Classic 1K (S50), MIFARE Classic 4K (S70), NTAG203 and other ISO 14443A cards, UID only, at up to 80 mm. For 125kHz EM4100 cards, use the L210-U.

The H210-U is a read-only 13.56MHz reader the size of a USB flash drive, 75 × 21 × 7 mm and about 10 g, that plugs straight into a USB-A port. It reads MIFARE Classic 1K/4K and NTAG203 UIDs at up to 80 mm and types them as 10-digit decimal numbers, also on Android through an OTG adapter.

Why integrators choose the H210-U

Plugs straight in — USB-A plug with no cable, 75 × 21 × 7 mm and about 10 g, with a protective cap and a key ring.
USB keyboard, no driver — enumerates as a human-input device and types the card number at the cursor.
Android through OTG — with an OTG adapter, card numbers go into any app on a phone or tablet that supports USB OTG.
10-digit decimal default — the 4-byte UID as a 10-digit number, with custom formats set before shipment.
LED and buzzer confirm each read, with a read time under 200 ms.

Where a stick reader makes sense

A desk pad needs a cable and a spot on the counter. The H210-U needs only a free USB-A port, which makes it the practical choice for laptops at mobile check-in points, hot desks, event and training registration, and field staff who carry a reader in a laptop bag. It also suits thin clients and all-in-one PCs where a pad would be in the way.

Output is the same as on the H110-U and H120-U desk pads: the card UID is typed as a 10-digit decimal number into the field that has the cursor, so the same software works with both. At about 10 g, and about 40 g in its small retail box with a plastic tray, it is also light to ship to distributed sites.

Using the H210-U with Android phones and tablets

Connect the stick through a USB OTG adapter (USB-A female to the phone's USB-C or micro-USB port). The phone or tablet must support USB OTG. The reader then behaves like an external keyboard: open any app, tap into a text field and present the card.

If the reader will live on a phone permanently, the H220-C plugs directly into USB-C without an adapter. The Android OTG checklist covers settings and common pitfalls. iOS is not on the H210-U's supported list.

H210-U or a desktop pad?

Choose the H210-U when portability or port-side mounting matters more than a fixed reading spot. For a counter where customers lay their card down, a pad such as the H110-U gives a larger, more obvious target and keeps the reader off the PC's port.
