Did you know? The first RFID patent was granted in 1973 to Mario Cardullo - for a highway toll transponder. It held just 16 bits of rewritable memory and was powered entirely by the reader's signal, no battery needed. That same passive principle still powers the contactless tags, NFC, and IoT sensors all around you today. The building blocks of connected devices are older than you would guess. fluidwire.com #IoT #RFID #Electronics #TechHistory

I'm hooked. Definitely more versatile than my #flipperzero overall, though not out of the box. Looking forward to getting a wide variety of modules.

So many of them are really cheap. Only ones that look expensive are the #UHF #RFID module and #infrared #camera modules.

I'll definitely have to configure both #cardputeradv differently - one for #pentesting & #recon ; one for environmental logging + #LoRa & #Mesh #MeshCore #Meshtastic

Análisis SEACOM del archivo — RFID en retail Chile, vigente:

Cuándo migrar de código barras a RFID:
SI tu tienda tiene >5.000 SKUs activos
SI inventario completo >4 veces/año
SI merma identificada >2% CMV
SI proveedores ya etiquetan en origen

NO si tienes <2.000 SKUs (ROI tarda)
NO si staff no opera dual RFID + barcode

Cliente moda: inventario 40h → 4h con 2 operadores.

Chameleon Ultra is a cool little #rfid #hacking gadget but the software ecosystem is a bloody mess. Just getting to the point where the CLI works has been an adventure.

Updated the #ChameleonUltra #RFID UF2 bootloader, now more simple to flash ;) no 'race timing issue". https://github.com/nieldk/ChameleonUltra/tree/UF2 Read instruction in. https://github.com/nieldk/ChameleonUltra/blob/UF2/firmware/tools/UF2_INSTALL.md

Be aware that you probably will need SWD in case you want to revert to 'normal'

The new generation chameleon based on NRF52840 makes the performance of card emulation more stable. And gave the chameleon the ability to read, write, and decrypt cards. - nieldk/ChameleonUltra

I've fished out a bunch of old ID badges and am having a go at reading them with #FlipperZero. Evidently I just leveled up, so... yay me?
