ngrep vs ChameleonMini

ngrep

ngrep is like GNU grep applied to the network layer. It's a PCAP-based tool that allows you to specify an extended regular or hexadecimal expression to match against data payloads of packets. It understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

well ... tsharek or ngrep (https://github.com/jpr5/ngrep/) should perform better than wireshark with its complete UI.

What NFC module is out there that can emulate all NFC technologies? (NTAG series, MIFAREs, etc)

Another alternative is to use something like Chameleon. They use an Atmel (general purpose microcontroller) instead of a specialized chip. However, that chip is currently out-of-stock, and the Chameleon is currently out-of-stock (or extremely expensive).
