My local coffee shop uses a paper card that is scribbled with signatures. It would probably be easy for me to fake it and get free coffee. The security requirements for this are pretty lenient. Of course, this doesn't mean that a more technical replacement such as Punchd shouldn't be secure, I just think it's interesting that security wasn't such a big deal before, but now it is, since there's a technical solution.
- dpark 15y agoFair enough. It's a low-security solution replacing a different low-security solution. I guess the difference with the technical security problem is that it scales. If I write an an app that does provides counterfeit punches, I can distribute it easily and nearly for free. Few people would go through the hassle of counterfeiting the cards, but they might install an app. I guess that if this gains traction and security proves to be a meaningful issue, plugging the hole should be easy enough.
