Frequently asked questions
What is in the Blank Programmable Cards category?
Rewritable T5577, EM4305 and UID-writable blanks — the programmable backbone every compatible 125 kHz credential is encoded onto. We list 70 compatible formats here, all engineered by specification to read on your existing readers, not generic look-alikes.
Are these genuine or compatible credentials?
Every credential is an independently manufactured compatible product, not an OEM-branded one. Security ID Systems is independent and not affiliated with any referenced manufacturer. Our credentials are encoded to present the identical data your readers already accept.
Can you supply formats not listed on the site?
Yes. The catalogue documents 369 compatible formats, but we regularly encode credentials for specialist or undocumented formats too. Send the part number printed on your card or a photo of the reader and we confirm compatibility before you order.
