Frequently asked questions
What is in the NFC Tags & Cards category?
NTAG and NFC Forum compliant cards and tags for NFC applications, encoding and consumer tap experiences, in bulk. We list 3 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.
