Does anyone know what chip type Ventra cards use? If so, is it possible to clone it to an implant? I thought it would probably be more convenient than having to take out the card from my wallet or using Apple Pay to pay for bus or train fare.
All I know is that the readers also accept normal contactless credit/debit cards, Apple Pay, Google Wallet, etc., so I would take a guess that they also have encrypted chips like EMV cards.

IIRC, not cloneable. DESFire isn’t susceptible like Mifare is.
I had a transit card that read like this (DESFire with ISO 7816-4) and it was labeled MasterCard on the front. It looks like the old Ventra cards were prepaid MasterCards.
Even if there was a DESFire workaround, I don’t know if you would be able to emulate whatever security provisioning MasterCard does to their chips. They have licensed facilities for that.
The Mastercard version is a bit misleading.
The NFC chip inside had nothing to do with the MasterCard usage, you had the option to enable MasterCard payments on the Orginal Ventra Card (grey one) which allowed you to use your loaded transit balance as a prepaid Mastercard too, however it only used a Magstrip on the back of the card for credit card purchases. The new Ventra card has no option for use as a Credit Card and has no Magstrip on the back.
I have had both of the Ventra cards pictured above.
From what I can tell, they both use HF RFID (13.56 MHz) but not sure about any of the other details.
