Safaricom is yet to finalise a plan to block customer contact details when making payments through Lipa na M-Pesa.
The planned move is aimed at curbing personal information from being traded to advertisers or leaking to fraudsters in line with data protection legal requirements.
The telco had earlier said that it would only display the first name of subscribers making payments through the platform and a few digits of their phone number, effectively hiding the contact of the customer.
Safaricom yesterday did not provide a new date for the rollout of the service but said it was racing to come up with a solution.
