How the compatible Generic Wiegand 32-bit (WIE32) works
The Generic Wiegand 32-bit (WIE32) is a dual-frequency credential operating on both 125 kHz LF and 13.56 MHz HF, so the compatible part must carry the correct data on whichever band your readers use. Its data structure is 32-bit: 12-bit site + 16-bit card, no parity (generic); also a 32-bit raw CSN passthrough variant (card serial, no FC/parity). When you present a credential, the reader decodes that exact structure and passes it to your access-control panel as a card number it recognises.
As a programmable blank, the Generic Wiegand 32-bit (WIE32) is the raw material the rest of the catalogue is built on. We supply it factory-fresh and rewritable on the Genuine NXP MIFARE Classic / T5577 / EM4305 platform, so you — or we — can encode it to emulate the proximity format your readers expect. It is the backbone of every 125 kHz compatible credential we ship.
To order, tell us the part number or format printed on your existing Standard / Generic card, along with your facility code and card-number range, and our specialists confirm the encoding before anything ships. Bulk and reorder quantities are welcome — pricing is a fraction of OEM list, and every credential is verified to read on your existing equipment.
