We offer worldwide shipping at a starting cost of $29.99. Please note that when ordering large batches of tokens, the delivery price increases.
Protectimus Limited is not responsible for the work performed by shipping services, for delays in shipping, or for parcels lost by shipping services, but we will take all possible, reasonable measures to facilitate the expeditious delivery of customer orders.


Depending on the laws of any given country, there may be additional fees (e.g. duties, taxes) associated with the passage of goods through customs. It is the buyer's responsibility to pay any duties and taxes required by his or her local customs authority.


Protectimus Slim NFC tokens use the TOTP time-based algorithm for generating one-time passwords. Thus, this product contains a built-in clock that may become desynchronized. Per RFC 6238, the time difference between the token and server should be monitored by the server software. There is no facility for token synchronization. Google Authenticator allows for a shift of more than 8 time intervals (4 minutes). A time desynchronization of less than 3 minutes is not covered by the Protectimus Slim NFC warranty.


Before ordering, carefully review the technical specifications of the Protectimus Slim NFC OTP tokens regarding compatibility with your infrastructure. If a token is found unsuitable because the user did not review the device's technical specifications before ordering, all costs for returning the device will be borne by the customer.
