I was in serious need of a bulk supply of proximity tokens for managing access to a small workshop, and after searching around online, I landed on the **100pcs T5577 EM4305 Rewritable 125KHz RFID Tag Writable Rewrite Duplicate Copy EM4100 Card Key Fob Proximity ID Token Keyfobs**. I needed something inexpensive but reliable that I could easily program and duplicate for various users without constantly buying new hardware or single-use tags. Getting a full hundred units in one go felt like the right move for this project.

Right out of the packaging, these tags felt sturdy enough for daily use, though they are clearly thin plastic cards, not heavy-duty key fobs. The best part about this batch is how wonderfully **rewritable** they are; I tested several of them, and the ability to **duplicate** or overwrite the data on the fly using my reader/writer has been invaluable for testing different access levels. They function perfectly on the standard **125KHz** frequency, which is exactly what my existing reader system uses.

Furthermore, since they support both the T5577 and EM4305 chips, I have great flexibility should I need to emulate different common card types—it’s truly a versatile set of **ID Tokens**.

What really sold me was the sheer quantity combined with the functionality. Being able to use them as **Writable Rewrite** backups or fresh keys means I won't run out anytime soon. Although there weren't many detailed reviews available when I purchased these, my personal experience confirms they perform exactly as advertised for cloning and reuse.

The basic card format means they fit easily into badge holders without adding bulk.

If you are managing a system that requires cloning or regularly reissuing low-frequency proximity access cards—whether for a small office, a gym, or even hobby projects—this massive pack of **100pcs T5577 EM4305 Rewritable 125KHz RFID Tags** offers unbeatable value. They are dependable and highly versatile.

Seriously, for anyone needing flexible, high-volume 125KHz RFID management tools, jump on this deal; these **Rewritable RFID Tags** are a fantastic purchase!
