At our hotel and discovered that one of our key cards doesn’t work. Looks like the clerk only programmed one of our two cards. Luckily I had my flipper! Read the key card that worked and then used NFC magic to write onto the blank card. Now we have two!
So that little guy works well?
I really like it. Has a ton of functionality for a little device. Most of which is beyond my expertise but it’s been fun to learn on.
Yes, they are popular at the office 🏢 here at GENERAL BYTES and you can store several cards into them. It's not a wonder tool or anything like it, more like a modern version of a Swiss army knife.
The price should be lower in my opinion as it doesn't do any rocket science and is less powerful than an entry level android so it should be priced about 50% cheaper but if you don't mind that, grab one and start hacking for fun and profit. 😉
Tip: get one of those silicon sleeves from AliExpress to protect your flipper as it doesn't like getting dropped to often. You can get one here: https://s.click.aliexpress.com/e/_EzbnBF9
You might have been able to use your phone and the NXP Tagwriter app (android) to do the same.
BTW: The IHG Hotel I stayed in last week had similar cards made from wood instead of plastic. They look super nice but are a bit more fragile than the plastic versions.
Do you happen to know if the cards can be reused? Would like to wipe and use again if possible.
Yes they can be reused, in fact that is exactly what your flipper did when you cloned your working card onto the 'defective' one. I often use them to program my guest Wi-Fi credentials on a card and leave one in my guest bedroom for guests to scan and connect to my Wi-Fi.
The memory available on these cards is usually limited to might not fit a complete wallet seed onto them but a bolt wallet should be possible. To find out the exact chip in the card (usually NXP NTAG 213, NTAG 216, or clone) use this app : https://play.google.com/store/apps/details?id=com.nxp.nfc.tagwriter
Dude that is a great idea! Thank you for sharing! 🙏
On a side note: the non writable UID error usually happens with cards that stick to the official standard. Writable UID tags can be purchased for cheap on AliExpress from unscrupulous sellers. They are often used to clone the 125khz tags used for entry systems for offices, garages, etc.
