An ok card issued after September 1, also called "Anbaili Promotion Points Card", can only be used by Anbaili's merchants, including Shibaiyi Store and Oriental Commercial Building (all of which have An Baili logo on their signboards).
The blue one you mentioned is called "ok membership card". You can look at the "ok Card Club" in official website, which can be used by all walks of life. The yellow and blue "ok point card" has a slightly smaller scope of use. In fact, it is the recharge card of the "ok membership card", and the points in the point card must be recharged to the membership card before they can be used.
The original ok promotion points cards (yellow and blue) will be used as before. Please refer to "OK Card Member Club" for details.
At present, the "Ambry Promotion Points Card" can only be used by An Baili's merchants. For example, in Nanjing Road Street, except New World, all other big companies are merchants of Ambry Group.
At present, Ambry's promotion points card is gradually being opened, such as paying water and electricity fees and charging mobile phone fees directly on the "ok card network". However, the "Ambry Promotion Card" will have the same function as other ok cards in the future (the validity period of the card is now 20 16).
