Usage

To use ovchipcardlib in a project in an event watching loop you could use the

following code.

from ovchipcardlib import Service
from time import sleep
from datetime import datetime

ovchip_username = 'OVCHIP_USERNAME'
ovchip_password = 'OVCHIP_PASSWORD'
card_name = 'Mijn OV-Chipkaart'


service = Service(ovchip_username, ovchip_password)
card = service.get_card_by_alias(card_name)

print('Monitoring card with number {}'.format(card.number))
print('Getting all historic transactions') # here we discard all the old
                                           # ones since we want to monitor
card.get_latest_transactions()
print('Got all transactions. Entering the monitoring loop...')
while True:
    for transaction in card.get_latest_transactions():
        now = datetime.now()
        time_shift = now - transaction.datetime
        delay_message = 'Delay of transaction logging :{}'.format(time_shift)
        body = '\n'.join((str(transaction), delay_message))
        print('Transaction logged at {}'.format(now))
        print(body)
        print(delay_message)
    sleep(60)
