Threats of exposure and boycotting/blacklisting the card making room for competitors.
Plenty of religious groups have the money to be able to start the "holy card". And there's plenty of businesses that'd be giddy to accept Jesus card.
Consider, for example, companies like hobby lobby or Chick-fil-A banning visa and promoting Jesus card.
It also wouldn't take much for such a card to advertise itself as kid friendly.
Thinking about it, I'm a little surprised this hasn't happened already.
Let’s be real, Chick-fil-A banning Visa would likely result in its bankruptcy.
Starting a holy card that doesn’t work at gas stations etc is an extremely uphill battle.
Do you mean like Greenlight?
What competitors? You mean a "Jesus Card" issued by Visa or Mastercard? At this point, it's basically an oligopoly. The only other real player is Amex, and they're a very distant third.
