Jedrek T5577 125kHz Writable PVC Cards

These are 100 blank CR80-format PVC cards with a T5577 chip that operates at 125kHz. They arrive with no data written and require a separate card writer to programme before any access control device will recognise them. Each card measures 86 by 56 by 0.8 cm and weighs about 65g per ten cards. They are water resistant and include a key ring for easy carrying.

Suitable for installers needing bulk 125kHz

The cards work with door entry systems, hotel locks, staff attendance, campus access, parking entry and similar 125kHz RFID readers. They are not for buyers who need cards pre-encoded from the factory, or for anyone who does not already own or plan to buy a compatible T5577 writer. They are also not for systems that operate on a different frequency or require a non-rewritable credential.

T5577 chip at 125kHz decides compatibility

The single specification that determines whether this is the right part is the T5577 chip running at 125kHz. If the target reader expects that exact chip and frequency, these blank cards can be written and reused. If the reader uses another chip type or frequency, the cards will not function.

Questions about this item

Does the card draw any power or generate heat when it sits on a reader all day?

No external power is required and the passive PVC card produces no heat or noise during continuous use.

What equipment do I need to write data onto these T5577 blanks before the door system will accept them?

A separate 125 kHz card writer is required; the access control unit itself cannot program the cards.

Will these CR80 cards work with the older 125 kHz proximity readers we already have installed?

Yes, they operate at 125 kHz with a 3–10 cm read range and are compatible with existing RFID door entry systems.
