12 PCS T5577 Thick Smart Cards, Contactless 125khz RFID Rewritable Proximity Clamshell Weigand Prox Card, Compatible with 1386 1326 H10301 Format Readers and Keyless Entry Access Control Systems

I bought these in order to copy my work key and gym key into these and I must say it is good quality definitely value for money, easy to use and great functionality. I will definitely be ordering more!!!

Worked for perfect for a gate card I needed made. My association charges $50 for new cards. I was able to copy my card and write to these in less than a minute. Worked perfectly!

Perfect to write spare badges onto for work. Quick and easy to write onto. Great quality for the price!

These worked. Bought a reader, didn't see it didn't write. Bought a writer. Neither read a gate card. Probably wrong type. Whatever. Then came the flipper zero. Read, saved, then wrote to these beauties. Perfect.

I struggled to find a rfid card with this clamshell style but I finally found it. It is very sturdy and I love the thickness, easy to program with my flipper zero and they are so worth the price. (Only about $1 per card)

Cheap but they work. Was able to copy building entrance cards for myself and friends to have extra for work.

They work perfectly
