The front of the card contains the brand name, logo (a diamond?), sponsoring bank name, and the phrase “electronic payment card”. I spoke with James Pearson at Reuters about the 16 digit number, and based on his research it does not appear to be directly related to the Foreign Trade Bank (FTB). Mr. Cockerell reports on his Instagram page that the card uses the same retail payment equipment as the Narae Card (which is controlled by the FTB), so that means the two banks (Daesong and FTB) have an established clearing mechanism to settle electronic balances (Q: Are other NK banks using this same equipment/part of the same network?). FTB is supposedly the official repository of the state’s hard currency reserves for the purposes of managing foreign trade and domestic hard currency transactions for imported goods, though it apparently does not have a monopoly on individual/company hard currency accounts. Daesong Bank (Taesong) is has been linked to the KWP’s Office 39.
The back of the card reads:
1. 카드앞면의 전자요소가 손상되지 않도록 주의하여주십시오.
Be careful not to damage the chip on the front of the card
2. 암호를 련속 3번 틀리게 입력하면 카드의 사용이 중지됩니다.
The card will stop working if you enter the wrong password 3 times.
3. 카드를 분실한 경우에는 즉시 카드발급지점에 알려주십시오.
If you lose the card, immediately notify the branch that issued the card.
4. 기타 제기되는 문제들은 카드발급지점에 문의하여주십시오.
For any other issue, consult the branch that issued the card.
This card is apparently for hard currency purchases only, and it was launched in early 2016. It is functionally the same as the Golden Triangle Bank Electronic Payment Card, Jonsong Electronic Payment Card, KoryoBank Electronic Payment Card, Narae Electronic Payment Card, Ryugyong Commercial Bank Electronic Payment Card, and Sowol Electronic Payment Card.
I should also mention that none of these are “debit cards” since they are not linked with a specific checking (demand) deposit. These are pre-pay cards only. These cards are essentially private digital currency issued by an established bank. The bank maintains control of the hard currency used to top off the cards, which it uses to generate income (float), while the card holder gains the convenience of not having to carry cash, which does offer some security from petty crime, but makes retail transactions more observable to security agencies.
Mr. Cockerell also posted the picture of a loyalty card for the Moran Shop (“Bar”):
He reports that “every time you spend money there it’s recorded on the card and when you reach $500 equivalent in total then there’s some free gift.”
