Worked Fine in My Application
After reading some of these reviews, I actually peeled off the contacts and looked at the chip underneath under my microscope. Yep, there is a chip there, with Vcc, Gnd, SCK and SDA connected with tiny gold wires. RST is not implemented. The actual chip is only about a millimeter square, which is why the card is perfectly flat. I am using the cards to save and load menu settings for a commercial convection oven controller. In this application it is simply an EEPROM, with no security or encryption whatsoever. I was pleasantly surprised.

Will not print on Zebra ZXP Series 3 printer
There is a slight bump on the blank side from the smart chip that causes a huge vertical smudge across the entire card. Rest of the card prints fine, but 20% of the card is smudged garbage.

Doesn't work on 7816 readers
Was looking for ISO 7816 smart card, but forgot to look at reviews (shame on me). Have to ditto Alex B's review. I have tried three different readers and all return "Unresponsive card (installed correctly?)".

Marklin 60135 locomotive card substitute
Work like a charm. I was looking for a substitute for the Marklin '60135 Locomotive Card'. Have about 120 locomotives and at $25 for 5 I figured there must be unbranded ones available for less. These are perfect. I bought 50 pcs already.

Would not work on any ISO-7816 readers
I tried these cards on all the ISO 7816 readers we own (Identiv SCR3310r1 & SCR3310r2, Identiv uTrust 4701F, HID OmniKey 5422, Belkin SmartCard reader) and none of the readers could read these cards, not even the serial # of the cards. In most cases, it would read as "no card inserted" or "card inserted incorrectly".When comparing to other brand name ISO 7816 cards, I can see the golden contact pads have a different trace patterns than a HID Crescendo or Taglio PIVkey, so I am fairly certain that these smartcards are not ISO 7816 at all. Likely meant for some other smart card protocol.

Returned. Didn't do what I needed
We tried buying this to replace a proprietary card. Unfortunately without the programming they didn't work for us
User
No instruction or software on how to use or program
Pretty much worthless unless you have software and instructions on how to use.
User
Do not buy
Cards are read write protected and are completely useless.
