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.
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).

A similar project is the Flipper Zero. Unfortunately, the device is sold out too.
