If you mean traditional Venezuelan credit cards, remember that the original problem is hyperinflation, this is exactly the kind of thing they want to avoid.
I don't see the opportunity being missed here.
I use my AMEX, BoFA VISA, citi MC, with absolutely no problems on venezuelan point of sales.
Bolivars are not worthless when you getting the full exchange value of it, they render worhtless when you put them in a savings account for 1 full year, at this moment, the rate of usd/ves has kept around 1:200k for around 2 months, this kinda gets some time for people to maneuver their VES, it changes hands really quick
Central bank rate is pretty much similar as "black market one" since 1 year ago. Sometimes is even better.
As of today, 1 USD from an USD credit card in venezuela exchanges to 203.639,64 [1] while 1 usd exchanged in the "black market" gives you 205.310.06 [2]
This is just a roundabout way of saying that the only way to not lose value is if you spend bolivars immediately.
Even if the exchange rate is stable for "around 2 months", this does not mean that the currency is keeping its purchasing power. It just means that the central bank has successfully managed to keep the currency peg for this period.
The advantage of Zelle is that unlike Visa, it is a dollarization tool. A Venezuelan merchant can directly earn U.S. currency.
The ones that do manage to get any savings will rush to the black markets to convert bolivars to USD or EUR. The ones that don't get any savings are SOL.
As someone who grew up with 30%-40% inflation a month, I find it really weird to see someone thinking any of that is cool.
Is cool that they do it, as it allows more payment methods to then and allows me to spend my USD, the more formal the business is, the more it will avoid using informal payments methods like zelle, so I do use my US creditcards in big chains, etc. As for every other aspect of our economy, im clearly hugely affected by it, me saying that POS taking usd cards is cool, doesnt mean i agree to our mess of an economy
I don't know if you miss the point that the official currency of venezuela is still the VES, and business have to still use VES for so many reasons, yes a big part of the VES gets exchange to USD but the main currency, still the VES
And yes, I understand that the economy is not de jure dollarized, so that there are still the need for bolivars at some point. My point though is that having a parallel, USD-pegged economy outside of the "official" markets would be better for the people than not having it.
I suspect a side benefit of dollarization is being able to avoid to declaring income. I doubt they are paying taxes in the USA either.
This leads to great disparities between official rates and secondary market rates. So if you are the one accepting credit cards, either you had to have different cash/card price tags (usually not acceptable for the card companies) or you simply don't accept card payments.
