My understanding is they were an equivalent and competition of businesses like Neteller, Skrill, (Transfer)Wise, Paypal. Not sure how clients would directly withdraw cash from them? These could be valid "cash transfers" to various subsidaries avoiding banking system for whatever reason. BTW there was an interesting "cash fever" months before outbreak of COVID, even Deutsche Bank in Germany was putting in their ATM areas messages "for withdrawals exceeding 10k eur notice us in advance", hadn't seen them ever before.
