We interpret the question to be “that the virtual credential should operate a speed comparable to an encrypted RFID card”.
In practice, the Safetrust wallet communicates at over 1Mbit/s at much greater distances than RFID credentials. Communication is fully encrypted end to end. When comparing a 125khz prox card at the same distance, the Safetrust Wallet will operate at the same speed but uses full encryption unlike the unencrypted prox card. A closer comparison of technology would be to compare either a Desfire/EV1/EV2 credential and the Safetrust Wallet. The Safetrust Wallet outperforms a Desfire card in both distance and credential transmission speed.
Finally, the Safetrust Wallet outperforms all RFID cards in relation to distance, where an RFID card must be within a short distance to absorb power and influence the magnetic reader field, the Safetrust Wallet can communicate at distances up to 150 feet.
