IEC specifies the application layer protocol of the standard transfer specification STS used for transferring units of credit and other management information from a point of sale POS system to an STS-compliant payment meter in a one-way token carrier system. It is primarily intended for application with electricity payment meters without a tariff employing energy-based tokens, but may also have application with currency-based token systems and for services other than electricity.

It is intended for use by manufacturers of payment meters that have to accept tokens that comply with the STS and also by manufacturers of POS systems that have to produce STS-compliant tokens and is to be read in conjunction with IEC x series.

Prices subject to change without notice.The key operational objectives of the association are to maintain the necessary infrastructure; promote the technology internationally and further develop the standard to meet emerging international demands for additional functionality. The Association ensures interoperability between system components from different manufactures of prepayment meter and vending systems by accrediting and maintaining a list of test laboratories that ensure compliance to STS standards.

The Association manages the availability of encrypted vending keys to manufacturing members via its key management centresand ensures consistent use of manufacturer identity codes as well as meter serial numbers. In keeping with the fast progressive technology, STS Association has established Working Groups for on-going standard enhancement projects.

Working Groupscomprising technical experts from STS Association member organizations and the industry are currently involved in a number of projects related to the ongoing maintenance of the standard, as well as new developments such as:. Secretariat: Mr. BoxFerndale,Johannesburg, South Africa. The standard transfer specification STS is a secure message protocol that allows information to be carried between point of sale POS equipment and payment meters.

It caters for several message types such as credit, configuration control, display and test instructions. It further specifies devices and codes of practice that allow for the secure management generation, storage, retrieval and transportation of cryptographic keys used within the system. The STS is deployed using various devices and other entities within the system. Examples of these are the key management centresecure module, prepayment meter, token, key load file, meter card, communications port, standard token translator, credit dispensing unit, system master station, cryptographic keys, supply group and operators like the utility, consumer, vendor, meter manufacturer and secure module manufacturer.

These entities are tagged with identifiers like country code, ISO BIN, supply group code, meter number, manufacturer number, tariff index, token identifier, key revision number and key type.

View Full Details and Buy.Each token is encoded with a unique Token Identifier TIDwhich has a limited range and will run out roll over on 24 November After this date all STS compliant meters will stop accepting credit tokens, unless an intervention takes place, which means that all these meters need to receive the TID Rollover Key Change with new base date before this date.

The STS Association has been in operation now for the past 25 years without any known compromise of its security level and vending keys. This risk is ever increasing due to the natural evolution of computing power, which roughly doubles every 18 months. It is therefore a mandatory requirement for all STS systems and products to comply with these standards and specifications before 24 November The following frequently asked questions attempt to provide STS users with guidelines and insight on how to deal with the above-mentioned issues.

Only STS Edition 2 compliant vending systems are able to generate the special key change tokens for all meters required before the TID rollover event on 24 November Secure modules complying with legacy STS Edition 1 specifications, will no longer be supported after Product certification services for vending systems with legacy STS Edition 1 certifications, will no longer be supported after Juneat which point all old certificates will be revoked. Support for all legacy STS Edition 1 products and services will cease after Certificates for vending systems certified to legacy STS Edition 1 specifications will be revoked after June Please contact your secure module supplier to check if your security module is able to receive a firmware update.

However, this functionality could only be tested since February when the required test tools became available.

There is an uncertainty about meters certified before Februaryso these meters need to be re-tested for TID rollover key change functionality. No action is required for meters certified after this date. For installed meters certified before Februaryone sample meter needs to be taken from the field and sent to the STSA test facility for re-certification of the TID rollover key change function.

One sample of each meter type, model and firmware version needs to be submitted. The testing fee will be paid by the STSA, but the sender has to pay for transportation cost of the samples to and from the test house. In the case where the sample meter fails the TID rollover key change test, all meters of that particular type, model and firmware version need to be replaced prior to the TID rollover key change event.

The utility should have recourse to the supplier of the failed meter type on the grounds that the TID rollover key change function has been a requirement since inception of STS. Negotiate with your secure module supplier to upgrade the firmware or to replace the hardware where this may be appropriate. All vending systems must comply with STS Edition 2 before Julyafter which certification services for vending systems supporting only legacy STS will cease. When a meter accepts a token, it stores the TID in order to prevent the same token of being accepted more than once.

At the time of creation of the token, the TID is calculated as the number of minutes that have elapsed since a given base date.

The TID is calculated from a given base date and has a life span of At the end of its life the TID memory in the meter has to be reset also known as TID rollover and the meter key has to be changed to prevent old tokens from being used again. Existing vending keys are linked to the base date and a key revision of 1.

For this base date the TID reaches its end of life on 24 November STS Edition 2 vending keys are linked to a base date and a new key revision.

For this base date the TID reaches its end of life in Do not underestimate the magnitude of this operation, so start as soon as possible. There is only a relatively short time left to the deadline. Select sample meters certified before February and get them re-tested. Replace those meters that are non compliant.

Join the STS user group discussions on the website and learn from the experience of others who are engaged in a similar program. Establish a project team to plan the operation well in advance and involve your meter suppliers and vending system suppliers. The purpose of the project should not be communicated to vendors and consumers as this may alert and cause existing fraudulent activities like ghost vending or meter tampering to take evasive action ahead of time. Demarcate meters into smaller groups and do a key change on one group at a time so that the installed base is done systematically under well controlled conditions.
