What is a T5577 RFID card?

It’s a contactless, rewritable card with a 125 kHz RFID chip, ideal for access control, time tracking, and identification. It arrives blank, without pre-printed designs or data, ready for programming and customization.

What are the main uses for these cards?

They’re perfect for business applications like securing office or hotel access, tracking employee attendance, managing memberships, enabling parking systems, or supporting electronic wallets and loyalty programs.

How does the T5577 compare to EM4200 or TK4100 cards?

Unlike the read-only EM4200 and TK4100, the T5577 is rewritable, with 330-bit EEPROM memory and flexible emulation of formats like HID Prox, EM4100, and Indala. It’s ideal for applications needing data updates or multiple formats.

Are these cards suitable for high-security environments?

They’re best for low-to-medium security due to limited encryption. For high-security needs, have a check of MIFARE DESFire products.

What are the technical specs of the T5577 chip?

The chip operates at 125 kHz (or 134 kHz in some configurations), with 330-bit EEPROM memory (10 blocks, 33 bits each), supporting ISO/IEC 11784/11785. It offers read/write functionality with password protection and emulation of multiple 125 kHz formats.

Can I print on these cards?

Yes, they’re compatible with most ID card printers (e.g., Zebra, Evolis, Fargo) using dye-sublimation or thermal transfer, allowing logos, IDs, or designs on their PVC or PET surface.

How do I program data onto these cards?

Use an RFID writer like Proxmark3 or Flipper Zero to encode data, such as access codes or IDs, in formats like 26-bit Wiegand, HID Prox, or EM4100. We offer programming guides or professional services for setup.

What customization options are available?

You can add printed designs, logos, or sequential numbering, choose glossy, matte, or frosted finishes, include magnetic stripes (LoCo/HiCo), or opt for pre-punched slots for lanyards or badge reels.

What’s the read range for these cards?

The read range is typically 2-10 cm, depending on the reader, antenna size, and environment, ensuring reliable proximity-based access control.

Can these cards emulate other RFID formats?

Yes, the T5577 can emulate formats like HID ProxCard II, EM4100, Indala, and others, making it versatile for cloning or integrating with existing 125 kHz systems.

Are these cards password-protected?

Yes, they support password protection with three access modes (direct, request, or password access), preventing unauthorized rewriting or data access.

What materials are these cards made from?

They’re crafted from durable PVC, PET or others with a laminated finish, ensuring resistance to water, dust, scratches, and wear, with optional protective overlays.

What are the size and weight of these cards?

They’re CR80 standard size (85.6 x 54 mm), 0.84 +/- 0.04 mm thick, and weigh about 5g, matching typical credit card dimensions.

How durable are these cards?

They’re waterproof, dust-proof, and bend-resistant, operating reliably from -20°C to +60°C and storing safely from -20°C to +65°C in 20%-90% RH humidity.

What’s the minimum order quantity (MOQ)?

The MOQ is 500 cards, packed 200 per box, with outer cartons of 1000 or 2000 cards.

Can I return these cards?

Unused cards in original packaging can be returned within 30 days. Printed or programmed cards are non-returnable unless defective.
