Technology is an interesting thing. On the one hand, RFID-enabled ID and even credit cards of various types can be read at a distance, making it possible to easily open doors or even pay for goods in some circumstances. This technology, in theory, would also make it possible for people to get this data without your approval.
But should we be worried? For answers, you can look at this CSO article, which argues that you probably don’t need to fret about your data being stolen this way. The most pertinent point the author makes is that most cards don’t even have this technology. On the other hand, as reported on Hackaday, it is possible to build a compact reader to “suck” data out of cards that do use this data transfer method. While your credit may not be in danger, there are other cards, such as those used for building access via RFID, that you still would want to keep secure.
All of that being said, you may or may not need the void wallet for your personal security, but as shown above, the two sides/band design actually looks like a pretty neat minimal wallet design. Additionally, it features, “An SMD reference sheet with the most common part footprints, conversions, hole sizes, pin pitch and two rulers (inches, centimetres).” Perhaps it would make a good present for the security conscious hacker in your life!
