Does anyone know what frequency thhis type of card uses? Is it 13.5mhz or 125khz?

I need to buy a card writer for this type of card but cant figure out which frequency it operates on. :S

The card in the picture is 125Khz card and is Read only. You cannot write to that. Instead you may use Mifare cards which use 13.5Mhz which are readable and writable. Cheers
 

Hello, need urgent help, do you know what is the frequency of Oyster transport for London RFID card?? This answer helps me with education purpose :)
Thank you for your answers.!
 

Most ticketing cards are using the Mifare (based on ISO/IEC 14443A) standard. You may want to check with a contactless reader, or check for the coil resonance (about 17-19 MHz) with a grid dipper or other suitable instrument.
