Cheap, simple to setup and works
They are key fobs. I had an old read write Chinese made machine easy to purchase. Wanted a couple of spares. Used 5 and all have worked. Saved me a total of £200. I purchased from another manufacturer and none of them worked. So incredibly happy. Next day delivery, cheap so worth a punt happy days🙂. Used alongside keys cut at Timmons. A problem solved in less than 48 hours.

Not compatible with Flipper zero
These do not perform in the same way as other T5577s I have bought. Not compatible with Flipper zero as it reads them as write only EM4100s.

Sadly these are now useless and not writable
Avoid. These are not T5577 tags they are unwritable EM410x tags. Utterly useless.

Works with Texecom Alarm
Bought a while ago, but none of these have missed a beat work everytime Used with texecom alarm systems as there tags are a bit different to others and worked all ok, Didnt work with paxton reader however

Super Alternative
Benutze die Tags mit einer Indexa-Alarmanlage. Da kostet ein RFID-Tag ~7€. Und der macht nicht mehr. Insofern kann ich die Dinger sehr empfehlen.

Great product
My building charges me $50 EACH for replacement fobs and my vacation home would only allow 4 fobs. These rewrite flawlessly and now I have ample fobs for myself and a number of friends as well.

HID not compatible and not mentioned (Avis Modifié)
J'avais été un peu rude lors de mon premier commentaire en mettant 1 étoile mais : 1) Le descriptif n'est pas assez clair sur le fait que les badges sont configurés en mode 125Khz ID et non pas 125Khz HID. C'est indiqué nul part et ça devrait l'être parce qu'avec un simple lecteur/"graveur" RFID, il n'est pas possible de changer le type d'accès. Il faut un Proxmark ou quelque chose de plus abouti en espérant que la puce utilisée soit compatible avec ces changements (ce qui est le cas du T5577). Enfin bref.. J'ai augmenté la note parce que le badge sont fonctionnels et donc le produit est bien. Les deux étoiles en moins sont clairement pour le descriptif qui peut induire en erreur les personnes qui débutent dans ce type de matériel.. Personnellement il a fallu pas mal de recherches avant de comprendre la raison pour laquelle mon scanneur 125 kHz HID n'arrivait pas a configurer et lire les badges livrés.
