wolfssl
The wolfSSL library is a small, fast, portable implementation of TLS/SSL for embedded devices to the cloud. wolfSSL supports up to TLS 1.3!
-
ChameleonMini
The ChameleonMini is a versatile contactless smartcard emulator compliant to NFC. The ChameleonMini was developed by https://kasper-oswald.de. The device is available at https://shop.kasper.it. For further information see the Getting Started Page https://rawgit.com/emsec/ChameleonMini/master/Doc/Doxygen/html/_page__getting_started.html or the Wiki tab above.

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.

ChameleonMini-rebooted
Chameleon Mini revE rebooted - Iceman Fork, the ChameleonMini is a versatile contactless smartcard emulator (NFC/RFID)
esp32s and esp8266s are my favorite pieces of hardware... for $2 you can setup a wifi access point

I would check out the Proxmark3 Github repo [0]. They have a cheatsheet [1] with the basics on how to get started. I also did a talk about RFID security last year about the basics [2]
To get started, the basics are: low freq (LF) is usually around 125khz and is rarely encrypted (HID Prox is the most common in the US). The data is often encoded in Wiegand format for access control systems (something to keep in mind when reading the raw data).
High freq (HF) (aka NFC) is ~13Mhz and is readable by most Android phones with NFC. Not all tag data can be read however. HF cards support a lot of different options including data storage (normally in a block layout with permissions to read and write depending on keys) and encryption (iCLASS and SEOS being the HID offerings and very common). Some can be cloned (like hotel cards) while others (like SEOS) require a downgrade attack to work correctly (SEOS -> normal SEOS reader -> Weigand data -> older style card like HID Prox).

As long as your custom service used the rpcap protocol I'd expect it to be possible. You may find this GitHub page informative, since it includes some rpcap source code and one of the main Wireshark developers appears to be a contributor there.
