Preface

My bank blocked my card due to a “high risk transaction”… again. This time they told me unblocking isn’t possible, and issued me a free replacement.

And as the title says, as a kid I wanted to try putting a cut-out bank card chip into a phone. Yes, I grew up in 2FF era.

The… thing

I also stripped the front foil because I was curious what’s under it. Nothing. The card is just flimsy without it, and the chip contacts raise above the card.

The abomination in comparison to real SIM cards:
The thing next to T-Mobile and GiffGaff SIMs

I have contactless and magnetic payments blocked. Only chip + PIN, thus the wear.

Attempts
  1. Samsung GT-S5830i (Android 2.3.6) - “Insert SIM”
  2. D-LINK DWM-222:
 -----------------------------
  Status   |             state: failed
           |     failed reason: sim-missing
           |       power state: on
  -----------------------------
  1. Alcatel 1066G:
    This is the only device with observable difference.
    Without SIM:
    Display saying "Insert SIM"
    With the… thing:
    Abomination inserted Display saying "Searching network"

At least it detects something. Contact and SMS storage says “SIM not initialized”
The “Searching network” eventually fails (what a surprise), and switches to “Insert SIM” after a few minutes.

About the blocking (unrelated to post)

Bureaucracy

Apart from what’s in the preface, the documents I signed still mention the standard 10 EUR charge. I asked to see what I am signing this time rather than just issuing the signature on their tablet and trusting the employee.
This time around, there is “fee will be individually assessed and charged” as well, and if I do get charged, I was told to dispute it at the bank.

Last time when giving me a card at the bank they just charged me anyway. Interestingly, that time the official reason was given as “card not delivered after 2 months”. If that were indeed true, why should that be my problem?

That was when I just opened the account. They told me that I could get the card immediately (“free”) rather than wait for it to arrive by mail.

Blocking process

Message from automated system approx. 12 hours before card blocking:

Plus, the payment worked on second attempt.

OH, FUN FACT: I didn’t even use the physical card, but a digital single-use card generated in the bank app.

So, they blocked physical card, after suspicious payment made using digital card, and even if that made sense, they waited 12 hours and let my second attempt through.

The other 2 times the blocking happened after donating to archive.org
